Adobe Photoshop CS2 version 9.0. Yeah, what a waste of potential, using that monster of a graphic editing program for my stupid little text bubbles.
MSPaint...and occasionally Abode Photoshop 7.0. Photoshop scares me, really. You plan to start your own comics too, Alpha Prime? (Yippee!) Edit: Doh! I totally forgot about IRFanView, which I use to resize, sharpen, crop and increase the brightness of my shots.
