I also have a copy of XnView on hand in case I need more "power." It is also free. Photoshop can read and write something like 14 formats, 3 of which are Photoshop only. Hope you realize how foolish it would be to save your pix to a one software only format. Irfanview does something like 24. XnView does 800+ A lot of my sales were international. Many countries are not quite up to the current "standards."
