Hi Andrew,
Yes that'd be pretty straightforward, it would depend on the hardware as to how it would perform though. I was actually looking for ideas for new shapes to put in the next version although I'd like to keep the overall thing very simple. I'll definately look at putting the images one in.
If you're happy to wait for the next version then it should be included, if you're in more urgent need then maybe ask Oliver nicely to add you as a beta tester :)
