I am just starting to do work with brushes/artistic images made from my photos, etc. I am interested in uploading as illustrative artwork as well as brush collections. The artwork I saved in PS as JPEGs at maximum quality. How should I save the brushes? I do have access to Illustrator as well, but I'm not very familiar with it. With PS, I see that they have their own PS esp format. I understand that with vector images, they can be scaled indefinitely.
Should brushes be uploaded as JPEGs? What additional formats do I need to make them sell better?
Any advice would be greatly appreciated!!!
