Merry and I were diving off Palos Verdes yesterday when a large catamaran cruised by. The Captain turned to come a little closer as his passengers waved. Now No Pressure knows who his real Daddy is.
Phil, my suspicion is that you need to bring the photo up in PS.com, then right click on it and click on "Copy Image Address" or something similar on you machine. You can then bracket the pasted URL with the image buttons. It works for stuff from Flickr. Send me a PM if you are having trouble with it.
