ETA: Never mind, I figured it out! I think it only looks choppy on my Windows Picture Viewer program. I just tried a test page with it saved as a .png and it looks fine here on pg.org.
I'm trying to post a digital baby announcement mock-up I did today. I have it saved on my computer as a .pspimage so that I can go in and edit the layers later. But everytime I try to save it as a .png or .jpg to post on here, it says that all the layers will be compressed. When I click okay, the image turns out to look really choppy and weird! :? Any tips? Thank you!
