I'm going to sound like a complete ignorant here but rather than waste time mucking about, I thought I'd ask the experts. I've always saved images as bitmaps but I've read here and there that you can save images with alpha channels. Am I correct in thinking that this means that the background is saved out as just that with the figure on its own layer? If so, then how is this done? - I can't find it in the manual (I may be missing it of course!). All thoughts welcome.
