SVG with IMG tags

/*
 * svgObject: a jQuery plugin, version: 0.1 (2010-09-03)
 * @requires jQuery v.1.4.2 or later
 *
 * svgObject parses all SVG images linked in the document as IMG tags, and replaces
 * the IMG tags with OBJECTs instead to make it all work nicely in FF 3.6+ and Safari 5+
 *
 * This:
 *
 * <img class="up svg" src="/images/up.svg" />
 *
 * is converted to the following, for Firefox:
 *
 * <object data="/images/up.svg" type="image/svg+xml" class="up svg"></object>
