If it can use svg, why not use that? SVG files can be a simple xml wrapper around a wide variety of graphic image formats which are embedded in the svg using the data-uri format, you know ... Anything that handles SVGs should be able to handle all the embeddable image formats, which should give you a way around image restrictions whatever it is would otherwise have.
