Paint Shop Pro for the Mac
I recommend Adobe Photo Elements.
I wish I could recommend Paint Shop Pro. I went to their website to see if they were planning on a Mac version and they say the Mac market is too small for the effort.
I can't believe Corel doesn't jump on Mac platform with PaintShop Pro X. Sure it may only have 4% of the market but Mac users easily could bring in 30% of the total sales for Corel. A lot of people still think 4% of the market means 4% of the revenue. cough** Windows users steal software ** cough
Mac users alone account for about 13% of all Microsoft Office sales. I bet the percentage is higher for creative software such as Dreamweaver and Photoshop.
