Maybe these sites will be of some help. I'd imagine there isn't much available though.

Here are stock photos that use the EPS format, which can be saved as CDR in CorelDraw.

According to this dated thread, it appears that CorelDraw comes with some free art.

Also, I don't know if this is helpful, but Inkscape to able to import CDR files and convert them to SVG.

Good luck!
