So... what is the best way to make help screens in AppGameKit?

I'm thinking about having the help screens as JPG's, but what is the best program to edit those screens in? one that can handle text and clipart.

I found that using OpenOffice.org Draw, and set the page to 33,86 x 16,66 cm, then export it to PNG, made a nice 1280*630 pixel file, just like i needed in my game.
