Core Attributes

The core attributes can be applied to this element.

align

This is a deprecated attribute. It specifies the alignment of the image. Its value can be bottom, or left, or middle, or right, or top. Since this a presentational attribute, it is preferable to use CSS instead.

left

Aligns the image to left edge of the line box

alt

This is a required attribute. The value of this attribute is a short description of the image. It is displayed when the image cannot be loaded. It may also be used by non-visual browsers.

border

This is a deprecated attribute. Its value is a number that specifies the width of the border in pixels that surrounds the image. Since this is a presentational attribute, it is preferable to use the CSS border property instead.

height

This attribute specifies the height of the image. Using this attribute may speed up the rendering of the page because the browser can allocate space for the image before it is fully loaded. Since this is a presentational attribute, it is preferable to use the CSS height property instead.

hspace

This is a deprecated attribute. Its value is a number that specifies the width in pixels of the right and left margins of the image. Since this is a presentational attribute, it is preferable to use the CSS margin property instead.

ismap

This attribute takes only one value and is specified as follows: ismap="ismap". It indicates that the image is part of an server-side image map.

longdesc

The value of this attribute is a URL to a document that has a description of the image. This will help those who are browsing the document non-visually. However, visual browsers such as Firefox, Internet Explorer, etc. do not provide any method to view the document specified in longdesc.
