SVG as an Image

SVG images can be used as an image format in a number of contexts. Many browsers support SVG images in:

HTML <img> or <svg> elements
CSS background-image

Gecko-specific contexts

Additionally, Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1) introduced support for using SVG in these contexts:

CSS list-style-image
SVG <image> element
SVG <feImage> element
Canvas drawImage function

Restrictions

For security purposes, Gecko places some restrictions on SVG content when it's being used as an image:

JavaScript is disabled.
External resources (e.g. images, stylesheets) cannot be loaded, though they can be used if inlined through BlobBuilder object URLs or data: URIs.
:visited-link styles aren't rendered.
Platform-native widget styling (based on OS theme) is disabled.

Note that the above restrictions are specific to image contexts; they don't apply when SVG content is viewed directly, or when it's embedded as a document via the <iframe>, <object>, or <embed> elements.
