I agree, I often find zipping .bmps often gives a smaller .zip than the one with the final .jpgs! Or you could try decrease the .jpg compression level so more detail, downside larger file. Plus not every one has a paint package that can read .PSD files if they wanted to edit them. For example: some early versions of Paintshop Pro, given away on cover discs, can't read layers. Another way is to use 2 nearly identical readme files. This is also a good way to give out bonuses. One readme is viewable by anyone reading it from the product page. The 2nd edited readme lives only found in the purchased version. The only difference is the 2nd file has a link to the full hi-res maps. That cuts on your bandwith and gives the customer an extra goodie.

Pinky - you left the lens cap of your mind on again.
