I have a mac os x and photoshop cs6. The problem I'm having is.... when I have finished a picture and saved it for web, I also use them as screen savers. If I want to show someone the picture, I double click on it  ( and here's the problem), it opens up photoshop again. Is there someway to save the picture so that I can just open it up with out it opening Photoshop everytime? I always save to .jpg.
