« XUL Reference home [ Examples | Attributes | Properties | Methods | Related ]

Summary

An element that displays an image, much like the HTML img element. The src attribute can be used to specify the URL of the image.

More information is available in the XUL tutorial.

Note: Prior to Gecko 8.0, images did not shrink down with the same ratio in both directions when specifying maximum sizes using maxheight or maxwidth. The new behavior aligns more with the HTML <img> element and shrinks both the width and height down proportionally.

Attributes: onerror, onload, src, validate

Properties: accessibleType, src

Style classes: alert-icon, error-icon, message-icon, question-icon

Examples

<image src='Firefoxlogo.png' width='135' height='130'/>

Attributes

onerror: Type: script code; This event is sent to an image element when an error occurs loading the image.

src: Type: URI; The URI of the content to appear in the element.

validate

Type: one of the values below

This attribute indicates whether to load the image from the cache or not. This would be useful if the images are stored remotely or you plan on swapping the image frequently. The following values are accepted, or leave out the attribute entirely for default handling:

always: The image is always checked to see whether it should be reloaded.
never: The image will be loaded from the cache if possible.

Properties

accessibleType: Type: integer; A value indicating the type of accessibility object for the element.

src: Type: URL; Gets and sets the value of the src attribute.
