I hope someone with a bit of experience can help me out here. I've discovered both Flex Projector and G.Projector as software for making various map projections and both look great. My problem is that I can't figure out how to import my base map into either one!

Flex Projector can supposedly import raster images (jpg, png, etc) but I don't see that option anywhere!

Same for G.Projector. I have an equirectangular image (2:1 ratio) and it doesn't recognize it.

Any thoughts?
