Icon Help! (Please Read)|PS3 Themes|Forum|PS3 Themes

Hey Guys,

I wanted to know where or how I can get Icons for the Themes I want to create. Also I don't mind learing how to make my own, so if any knows a link to a good video tut or text tut  to help guide me on how to create the icons and what programs I need to do this, that would be awesome. I have the latest PhotoShop but I dont understand How you create them or where to get standard ones to at least alter and put your own touches on . The Icons I have downloaded to my computer I can't open them due to them being .pt3 files and I have quite got the understanding on how to open them yet.

If anyone could help I would appreciate it greatly.
