• অনুমোদিত কনটেন্ট নেই, এটি একটি বাতিল এলিমেন্ট।

Usage note: Omitting this attribute indicates that the image is a key part of the content, but no textual equivalent is available. Setting this attribute to the empty string indicates that this image is not a key part of the content; non-visual browsers may omit it from the rendering.

border Deprecated since HTML4.01, Obsolete since HTML5

The width of a border around the image.

crossorigin HTML5

This enumerated attribute indicates if the fetching of the related image must be done using CORS or not. CORS-enabled images can be reused in the <canvas> element without being tainted. The allowed values are:

anonymous

A cross-origin request (i.e. with Origin: HTTP header) is performed. But no credential is sent (i.e. no cookie, no X.509 certificate and no HTTP Basic authentication is sent). If the server does not give credentials to the origin site (by not setting the Access-Control-Allow-Origin: HTTP header), the image will be tainted and its usage restricted..

use-credentials

A cross-origin request (i.e. with Origin: HTTP header) is performed with credential is sent (i.e. a cookie, a certificate and HTTP Basic authentication is performed). If the server does not give credentials to the origin site (through Access-Control-Allow-Credentials: HTTP header), the image will be tainted and its usage restricted.

When not present, the resource is fetched without a CORS request (i.e. without sending the Origin: HTTP header), preventing its non-tainted used in <canvas> elements. If invalid, it is handled as if the enumerated keyword anonymous was used. See CORS settings attributes for additional information.

height

The height of the image in HTML5 CSS pixels, or HTML 4 in pixels or as a percentage.

hspace Deprecated since HTML4.01, Obsolete since HTML5

The number of pixels of white space to insert to the left and right of the image.

ismap

This Boolean attribute indicates that the image is part of a server-side map. If so, the precise coordinates of a click are sent to the server.

Usage note: This attribute is allowed only if the <img> element is a descendant of an <a> element with a valid href attribute.

longdescHTML 4 only

The URL of a description of the image to be displayed, which supplements the alt text. In HTML5, use a regular <a> element to link to the description.

name Deprecated since HTML4.01, Obsolete since HTML5

A name for the element. It is supported in HTML 4 only for backward compatibility. Use the id attribute instead.

src

Image URL, this attribute is obligatory for the <img> element.

width

The width of the image in pixels or percent.

usemap

The partial URL (starting with '#') of an image map associated with the element.

Usage note: You cannot use this attribute if the <img> element is a descendant of an <a> or <button> element.

vspace Deprecated since HTML4.01, Obsolete since HTML5

The number of pixels of white space to insert to above and below the image.

Supported image formats

The HTML standard doesn't give a list of image format that must be supported, so each user agent supports a different set of formats. Gecko supports:

• JPEG
• GIF, including animated GIFs
• PNG
• APNG
• SVG
• BMP
• BMP ICO
• PNG ICO

Interaction with CSS

Regarding CSS, an <img> is a replaced element. It has no baseline, meaning that, when used in a inline formatting context with vertical-align: baseline, the bottom of the image will be posed on the container's baseline.

An image may have an intrinsic dimension, but not necessarily, depending of its type. A SVG image has no intrinsic dimension, a raster image has one.
