What tag specifies the insertion. We add images to the WEB page, as well as video and audio! Set the dimensions of the image
Before answering the question " how to insert a picture in HTML?“, it should be noted that it is not worth overloading web pages with a huge amount of graphic material, since this will not only improve the visual perception of the resource by the user, but will also increase the page loading time.
When creating websites, the most commonly used graphic formats are PNG, GIF and JPEG, and for design work with images - graphics editor Adobe Photoshop, which has rich capabilities for compressing and resizing images without losing quality, which is incredibly important for web development.
How to insert an image in HTML?
To insert an image into an HTML page, use a single simple tag:
,
where xxx is the image address. If the image is in the same directory as the page, the tag will look like:
However, high-speed and stable Internet has not yet reached all corners of the globe, and it happens that the image on the website simply does not load. For such cases, there is the concept of alternative text.
It is shown in place of the picture when it is unavailable, loading, or in the browser operating mode “without pictures”. It is added using alt attribute tag .
Example of adding alternative text to a graphic file:
Assigning image sizes in HTML
In order to change the display dimensions of a graphic file, use the height and width tags, where height is the height and width is the width, measured in pixels.
When using these attributes, the browser first allocates space for graphic content, prepares the overall page layout, displays text, and then loads the image itself.
The drawing is placed in a rectangle with given dimensions, and if the parameters are smaller or larger than the original ones, the picture is stretched or compressed.
If the height and width attributes are not used, the browser loads the image immediately, delaying the display of text and other page elements.
These parameters can be specified both in pixels (the size of the picture is constant and does not depend on the user’s screen resolution) and in percentages (the size of the picture depends on the screen resolution).
For example:
It should be remembered that at the moment when you change the original size of the image, it is necessary to maintain its proportions.
To do this, it is enough to specify the value of only one of the parameters ( width or height), and the browser will calculate the value of the second one automatically.
Image location in HTML
As with many HTML tags, Apply the align attribute, which aligns the image:
- the picture is located above the text;
- the picture is located below the text;
- the picture is located to the left of the text;
- the picture is located to the right of the text.
Picture link
This is done as follows:
As you can see, a graphic insert can be a link and, when clicked, redirect to any address written in full or abbreviated form.
How can I make an image a background in HTML?
The image can not only be inserted onto the page as a visible object, but also made into the background. To define an image as a background, you need to specify the background=”xxx” attribute in the tag, where xxx is the address of the image, specified in the same way as in the examples above.
For example, let's set the following texture image as a background image:
Save the image in a folder with a prepared page and write the following lines:
Background with text.
The background image on the page is set.
Hello dear blog readers! In this article you will learn everything about how to insert an image into an html page. Do you have several images that you want to put on your page or do you want to put a logo on your site? All this is easy. After reading this article, you will be able to insert pictures into your html pages without any difficulties. To do this, we will talk in detail about img tag and its attributes, we'll take a quick look at graphic file formats such as gif, jpeg and png, and also look at new HTML5 features that make it easier to insert video and audio into your site.
Due to the fact that graphic data and html text cannot be combined in one file; to display them on the site, a different approach is used than with other elements of html pages. First of all, graphic images, and other multimedia data is stored in separate files. And to implement them into a web page, they use special tags that contain links to these separate files. In particular, such a tag is img tag. Having encountered such a tag with an address, the browser first requests the corresponding file with an image, audio or video from the Web server, and only then displays it on the Web page.
All graphic images and, in general, any data that is stored in files separate from the web page are called implemented page elements.
Before inserting pictures and looking at the “img” tag in detail, it’s worth learning a little about graphic formats.
Graphic image formats.
There are many different graphic formats, but browsers only support a few. Let's look at three of them.
1. JPEG format(Joint Photographic Experts Group). Quite a popular format used for storing images. Supports 24-bit color and keeps all halftones in photos unchanged. But jpeg does not support transparency and distorts small details and text in images. JPEG is used primarily for storing photographs. Files in this format have the extensions jpg, jpe, jpeg.
2. GIF format(Graphics Interchange Format). The main advantage of this format is the ability to store several images at once in one file. This allows you to create entire animated videos. Secondly, it supports transparency. The main drawback is that it supports only 256 colors, which is not suitable for storing photos. GIF is mainly used to store logos, banners, images with transparent areas and containing text. Files in this format have the extension gif.
3. PNG format(Portable Network Graphics). This format was developed as a replacement for the legacy GIF and, to some extent, JPEG. Supports transparency, but does not allow animation. This format has a png extension.
When creating websites, they usually use images in JPEG or GIF format, but sometimes they use PNG. The main thing is to understand in which cases which format is better to use. In short:
- GIF is used primarily for animation;
- PNG is the format for everything else (icons, buttons, etc.).
JPEG is best used for storing photographs or grayscale images that do not contain text;
Inserting images into html pages
So, how do you insert an image onto a web page? You can insert an image using a single img tag. The browser places the image at the location on the web page where it encounters the img tag.
Code for inserting images into html the page looks like this:
This html code will place on the web page an image stored in the image.jpg file, which is located in the same folder as the web page. As you may have noticed, the address of the picture is indicated in src attribute. I already told you what it is. So, the src attribute is a required attribute that serves to indicate the address of the file with the image. Without the src attribute, the img tag is meaningless.
Here are a few more examples of specifying the address of a file with an image:
This html code will insert an image on the page called image.jpg, which is stored in the images folder located at the root of the website.
The src attribute can contain more than just relative links to images. Since images are stored online along with html pages, so each image file has its own url. Therefore, you can insert the image url into the src attribute. For example:
This code will insert an image from the site mysite.ru onto the page. A URL is typically used when you are pointing to an image on another site. For images stored on your site, it is better to use relative links.
The img tag is an inline element, so it is better to place it inside a block element, for example inside the “P” tag - paragraph:
Let's practice and paste into our page from previous articles about html image. I will create an “images” folder next to the html file of my page and place a “bmw.jpg” image file there, which looks like this:
Then the html code of the page with the inserted image will be like this:
And look at the display result in the browser:
As we see, there is nothing complicated about placing images on web pages. Next, let's look at a few other important attributes of the "img" tag.
The alt attribute is a fallback option
Because image files are stored separately from web pages, the browser has to make separate requests to retrieve them. But what if there are a lot of images on the page and the network connection speed is low, then loading additional files it will take considerable time. And it’s even worse if the image was deleted from the server without your knowledge.
In these cases, the web page itself will load successfully, only white rectangles will be displayed instead of images. Therefore, to tell the user what the image is, . Using this attribute, you specify the so-called replacement text, which will be displayed in an empty rectangle until the image is loaded:
And this is roughly what it looks like:
Set the dimensions of the image
There are still a couple of img tag attributes you should know about. This is a couple of attributes width And height. You can use these to specify the image dimensions:
Both attributes indicate the size in pixels. The width attribute tells the browser how wide the image should be, and the height attribute how tall it should be. These two attributes can be used together or separately. For example, if you specify only the width attribute, then the browser will automatically select the height in proportion to the specified width and also in the case of using only the height attribute. If you do not specify these attributes at all, the browser will automatically determine the size of the image before displaying it on the screen. It is only worth noting that specifying the image sizes will slightly speed up the browser when displaying the page.
That’s all about inserting images onto pages for now, then we’ll look at how to insert audio or video onto a website...
Inserting video and audio using HTML 5
The new html5 specification introduces several new tags that make it very easy to embed media files. This primarily applies to video and audio.
To insert audio HTML5 provides paired tag AUDIO. The address of the file in which the audio clip is stored is indicated using the src attribute that is already familiar to us:
The “audio” tag creates a block element on the page. By default, the browser will not play the audio clip. For it to do this, you need to specify a special attribute in the audio tag autoplay. Special because it doesn't matter. The mere presence of this attribute in the tag is enough for it to take effect.
By default, the audio clip is not displayed on the web page. But if you put an attribute without a value in the “audio” tag controls, the browser will display controls for playing the audio clip in the place on the web page where the audio tag is placed. They include a play/pause button, a playback bar, and a volume control.

How to make a table in html
Let's give an example, html code:
Example table Column 1 Column 2
Pay attention to the cell
Now let's take a closer look at all the tag attributes
| or lines | ||||||||||

2. Property background="URL" - sets the background image. Instead of the URL, the address of the background image should be written. Example
Converts to the following on the page: In the example above, our background image is located in the img folder (which is in the same directory as the html page), and the image is called fon.gif. Please note that in the tag we added style="color:white;" . Since the background is almost black, to prevent the text from blending into the background, we made the text white. 3. Property bgcolor="color" - sets the background color of the table. You can choose any color from the entire palette (see codes and names of html colors) 4. Property border="number" - sets the thickness of the table border. In previous examples, we specified border="1" , which means the border thickness is 1 pixel. 5. Property bordercolor="color" - sets the color of the border. If border="0" then there will be no border and the border color will have no meaning. 6. Property cellpadding="number" - indent from the frame to the cell contents in pixels. 7. Property cellspacing="number" - the distance between cells in pixels. 8. Property cols="number" - the number of columns. If you do not set it, the browser itself will determine the number of columns. The only difference is that specifying this parameter will most likely speed up the loading of the table. 9. Property frame="parameter" - how to display borders around the table. Can take the following values:
10. Property height="number" - sets the height of the table: either in pixels or in percentages. 11. Property rules="parameter" - where to display borders between cells. Can take the following values:
