HTML Images
Images can improve the design and the appearance of a web page.
Example
Example
Example
HTML Images Syntax
The HTML tag is used to embed an image in a web page.
Images are not technically inserted into a web page; images are linked to web pages. The tag creates a holding space for the referenced image.
The tag is empty, it contains attributes only, and does not have a closing tag.
The tag has two required attributes:
Syntax
The src Attribute
The required src attribute specifies the path (URL) to the image.
Note: When a web page loads, it is the browser, at that moment, that gets the image from a web server and inserts it into the page. Therefore, make sure that the image actually stays in the same spot in relation to the web page, otherwise your visitors will get a broken link icon. The broken link icon and the alt text are shown if the browser cannot find the image.
Example
The alt Attribute
The required alt attribute provides an alternate text for an image, if the user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).
The value of the alt attribute should describe the image:
Example
If a browser cannot find an image, it will display the value of the alt attribute:
Example
Tip: A screen reader is a software program that reads the HTML code, and allows the user to «listen» to the content. Screen readers are useful for people who are visually impaired or learning disabled.
Image Size — Width and Height
You can use the style attribute to specify the width and height of an image.
Example
Alternatively, you can use the width and height attributes:
Example
The width and height attributes always define the width and height of the image in pixels.
Note: Always specify the width and height of an image. If width and height are not specified, the web page might flicker while the image loads.
Width and Height, or Style?
The width , height , and style attributes are all valid in HTML.
However, we suggest using the style attribute. It prevents styles sheets from changing the size of images:
Example
Images in Another Folder
If you have your images in a sub-folder, you must include the folder name in the src attribute:
Example
Images on Another Server/Website
Some web sites point to an image on another server.
To point to an image on another server, you must specify an absolute (full) URL in the src attribute:
Example
Notes on external images: External images might be under copyright. If you do not get permission to use it, you may be in violation of copyright laws. In addition, you cannot control external images; they can suddenly be removed or changed.
Animated Images
HTML allows animated GIFs:
Example
Image as a Link
To use an image as a link, put the tag inside the tag:
Example
Image Floating
Use the CSS float property to let the image float to the right or to the left of a text:
Example
The image will float to the right of the text.
The image will float to the left of the text.
Tip: To learn more about CSS Float, read our CSS Float Tutorial.
Common Image Formats
Here are the most common image file types, which are supported in all browsers (Chrome, Edge, Firefox, Safari, Opera):
Abbreviation | File Format | File Extension |
---|---|---|
APNG | Animated Portable Network Graphics | .apng |
GIF | Graphics Interchange Format | .gif |
ICO | Microsoft Icon | .ico, .cur |
JPEG | Joint Photographic Expert Group image | .jpg, .jpeg, .jfif, .pjpeg, .pjp |
PNG | Portable Network Graphics | .png |
SVG | Scalable Vector Graphics | .svg |
Chapter Summary
- Use the HTML
element to define an image
- Use the HTML src attribute to define the URL of the image
- Use the HTML alt attribute to define an alternate text for an image, if it cannot be displayed
- Use the HTML width and height attributes or the CSS width and height properties to define the size of the image
- Use the CSS float property to let the image float to the left or to the right
Note: Loading large images takes time, and can slow down your web page. Use images carefully.

>
Example

>
img:hover box-shadow: 0 0 2px 1px rgba(0, 140, 186, 0.5);
>
Responsive Images
Responsive images will automatically adjust to fit the size of the screen.
Resize the browser window to see the effect:
If you want an image to scale down if it has to, but never scale up to be larger than its original size, add the following:

Center an Image
To center an image, set left and right margin to auto and make it into a block element:
Example
Polaroid Images / Cards
Example
div.polaroid <
width: 80%;
background-color: white;
box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
>
div.container text-align: center;
padding: 10px 20px;
>
Transparent Image
The opacity property can take a value from 0.0 — 1.0. The lower value, the more transparent:

Note: The filter property is not supported in Internet Explorer or Edge 12.
Example

Responsive Image Gallery
CSS can be used to create image galleries. This example use media queries to re-arrange the images on different screen sizes. Resize the browser window to see the effect:
Example
.responsive <
padding: 0 6px;
float: left;
width: 24.99999%;
>
@media only screen and (max-width: 700px) .responsive width: 49.99999%;
margin: 6px 0;
>
>
@media only screen and (max-width: 500px) .responsive width: 100%;
>
>

Image Modal (Advanced)
This is an example to demonstrate how CSS and JavaScript can work together.
First, use CSS to create a modal window (dialog box), and hide it by default.
Then, use a JavaScript to show the modal window and to display the image inside the modal, when a user clicks on the image:
Example
// Get the modal
var modal = document.getElementById(‘myModal’);
// Get the image and insert it inside the modal — use its «alt» text as a caption
var img = document.getElementById(‘myImg’);
var modalImg = document.getElementById(«img01»);
var captionText = document.getElementById(«caption»);
img.onclick = function() modal.style.display = «block»;
modalImg.src = this.src;
captionText.innerHTML = this.alt;
>
// Get the element that closes the modal
var span = document.getElementsByClassName(«close»)[0];
// When the user clicks on (x), close the modal
span.onclick = function() <
modal.style.display = «none»;
>
