Try it Yourself »HTML Images Syntax
In HTML, images are defined with the
<img>
tag.The
<img>
tag is empty, it contains attributes only, and does not have a closing tag.The
src
attribute specifies the URL (web address) of the image:The alt Attribute
The
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
<img src='img_chania.jpg' alt='Flowers in Chania'>
Try it Yourself »If a browser cannot find an image, it will display the value of the
alt
attribute:Example
<img src='wrongname.gif' alt='Flowers in Chania'>
Try it Yourself »Note: The
alt
attribute is required. A web page will not validate correctly without it.Image Size - Width and Height
You can use the
style
attribute to specify the width and height of an image.Example
<img src='img_girl.jpg' alt='Girl in a jacket'>
![Html download image link Html download image link](/uploads/1/2/5/4/125438792/635402976.jpg)
Alternatively, you can use the
width
and height
attributes:Example
Free Photo Gallery Html Code
<img src='img_girl.jpg' alt='Girl in a jacket' width='500' height='600'>
Try it Yourself »The
width
and height
attributes always defines 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 page might flicker while the image loads.
Width and Height, or Style?
The
width
, height
, and style
attributes are valid in HTML.However, we suggest using the
style
attribute. It prevents styles sheets from changing the size of images:Example
<!DOCTYPE html>
<html>
<head>
<style>
img {
width: 100%;
}
</style>
</head>
<body>
<img src='html5.gif' alt='HTML5 Icon' width='128' height='128'>
<img src='html5.gif' alt='HTML5 Icon'>
</body>
</html>
Try it Yourself »<html>
<head>
<style>
img {
width: 100%;
}
</style>
</head>
<body>
<img src='html5.gif' alt='HTML5 Icon' width='128' height='128'>
<img src='html5.gif' alt='HTML5 Icon'>
</body>
</html>
Images in Another Folder
If not specified, the browser expects to find the image in the same folder as the web page.
However, it is common to store images in a sub-folder. You must then include the folder name in the
src
attribute:Example
<img src='/images/html5.gif' alt='HTML5 Icon'>
Try it Yourself »Images on Another Server
Some web sites store their images on image servers.
Actually, you can access images from any web address in the world:
Example
<img src='https://www.w3schools.com/images/w3schools_green.jpg' alt='W3Schools.com'>

Animated Images
HTML allows animated GIFs:
Example
<img src='programming.gif' alt='Computer Man'>
Try it Yourself »Image as a Link
To use an image as a link, put the
<img>
tag inside the <a>
tag:Example
<a href='default.asp'>
<img src='smiley.gif' alt='HTML tutorial'>
</a>
Try it Yourself »<img src='smiley.gif' alt='HTML tutorial'>
</a>
Note:
border:0;
is added to prevent IE9 (and earlier) from displaying a border around the image (when the image is a link).Image Floating
Use the CSS
float
property to let the image float to the right or to the left of a text:Example
<p><img src='smiley.gif' alt='Smiley face'>
The image will float to the right of the text.</p>
<p><img src='smiley.gif' alt='Smiley face'>
The image will float to the left of the text.</p>
Try it Yourself »The image will float to the right of the text.</p>
<p><img src='smiley.gif' alt='Smiley face'>
The image will float to the left of the text.</p>
