[Clipart] CChost: Imbedded images in SVG's

[ryan lerch]

At the moment, on cchost, someone can submit an svg file with an
imbedded image in it, and it still gets through to the library.

see examples:
http://openclipart.org/cchost/media/files/ryanlerch/112
http://openclipart.org/cchost/media/files/nujunto/93

Also what would the best way of filerting these out?
Would it be to scan the SVG for the <image\> tag and reject all SVG's
that contain this?
If this is the case, should rejecting SVG's with scripts be also done here?
see bug:
