Regarding editing buttons with the Gimp, I just found this online:
I worked for a few years w/a Photoshop user (I think he had PS CS).
The caveats I learned from sharing files between the Gimp and PS were (from memory):
1. can't use masks in the Gimp and save to psd - they won't make it. Never figured out if the Gimp properly read in mask from PS though.
2. text layers just get rendered as pixel info - still look the same, but cannot be dynamically altered.
That would explain my confusion as described in post 487. I guess I'll have to pick up a copy of Photoshop. Can anybody give me some advice on what version to get? All I want to do is open up PSDs and move buttons around. In other words an older, cheap version would be great if it will allow me to do that.
