5.10. Image: IMG

The <IMG> element refers to an image or icon via a hyperlink (see 7.3, "Simultaneous Presentation of Image Resources").

HTML user agents may process the value of the ALT attribute as an alternative to processing the image resource indicated by the SRC attribute.

NOTE - Some HTML user agents can process graphics linked via anchors, but not <IMG> graphics. If a graphic is essential, it should be referenced from an <A> element rather than an <IMG> element. If the graphic is not essential, then the <IMG> element is appropriate.

Attributes of the <IMG> element:

ALIGN

alignment of the image with respect to the text baseline.

• `TOP' specifies that the top of the image aligns with the tallest item on the line containing the image.

• `MIDDLE' specifies that the center of the image aligns with the baseline of the line containing the image.

• `BOTTOM' specifies that the bottom of the image aligns with the baseline of the line containing the image.

ALT

text to use in place of the referenced image resource, for example due to processing constraints or user preference.

ISMAP

indicates an image map (see 7.6, "Image Maps").

SRC

specifies the URI of the image resource.

NOTE - In practice, the media types of image resources are limited to a few raster graphic formats: typically `image/gif', `image/jpeg'. In particular, `text/html' resources are not intended to be used as image resources.

Examples of use:

    <IMG SRC="triangle.xbm" ALT="Warning:"> Be sure
    to read these instructions.

    <a href="http://machine/htbin/imagemap/sample">
    <IMG SRC="sample.xbm" ISMAP>
    </a>
