I am going to be training a bunch of photographers on pictures to exe in a few days. I know how to use it well, but in anticipating their questions, realize that I am not in good control of pre-editing pictures to make sure they are as full screen as possible. My images are using only the central portion of the screen, and I have resaved them multiple times in photoshop trying to get the best pixel size and maximize the monitor real estate. Any tips here? I couldn't spot an easy answer in help or the tutorials or these posts. If this is a newbie question, I do apologize! Thank you!
