I'm making myself a new shop banner, and I'm wondering how you guys save your image files, and if there is really any difference. Like is .jpg any better than .bmp? I always have just saved as what my computer defaulted to in the past, but is one format better? Also, is this GIMP i keep seeing mentioned on here easy to use? I use MS paint for all my graphics, cause it's really easy for me to understand. I'd like to be able to do something fancier, but not if it'll take me 3 hours to make a banner for my shop.
