Hi Daeben. GIMP is free image editing software that some of the mod makers/mergers are using. BayouBlonde (another forum member) was also new to mods, taught herself how to use it and made a tutorial and some additional tips for the rest of us. I know Lewanda uses Paintshop Pro. I don't know if it's free. However, some software comes with a 30-day free trial period. Just a thought since the program you're currently using is limited. Modding is great fun and helps keep me interested in playing while I watch for my last 2 bugs for my collection! YESSSS!!!! Make that 1 bug!
