Have upgraded occasionally, but the new features haven't been as great as they sounded and after 2.0, PSE lost its integral browser. (It's now really two programs that swap back and forth.) I've sometimes found it on eBay to send to relatives.

I've rarely posted a photo straight from the camera; there's almost always something to clean up. Straighten the horizon and click on each of the "enhance" options to see what they'll do. (Just back them out or try in a different order if no good.) Usually they help!
