Picture Navigation While Editing Pictures

What i would like to see is the ability to move one picture foward or one picture backwards while you are in the Edit Picture menu. I don't know about other people but i like to uplod an album of picutre and then go edit them. As it stands, you hace to click on the picutre edit it, then go back to the same picture and advance to the next pic or go back to the first page and move to the next picture that needs work. What i think would be great is a navigation menu in the same area as "Edit Photo" or mabye a better spot would be under the thumb in the right hand corner,

thanks
