i disagree heartily with the idea that files must be saved at maximum size in PSE. Your best bet to convince yourself of this is to save at 10, 9, and 8 and then print a little swatch of it (around 4"x4" should do it) to see for yourself when the compression results in a "lossy" image, e.g. one that shows a degradation of quality. I routinely save at 8-9 compression because I don't think I need 8 MB for a piece of patterned paper and the old hard drive fills up WAY too fast with such huge files. My papers are rarely over 4 MB. My prints look as got as my screen; in fact I am always super excited to see my papers and elements in print! As far as .pngs go, this file format is just used for elements or thing that have transparency to them -- not sheets of paper.
