Making a Bottom Bar image

[Busser]

hi i'm trying to make a image for the bottom bar "image" i know it is to be 1024 X 85 pixels. But wat i want to do it take a picture and in some parts i want it lower and in other parts i want it higher. I also want to be able to see the game thru the lower parts like i see in some of the different ui mods ppl have made. there image is 1024 x 85 but the image is not the whole size and yo ucan see the game thru the image in the lower parts so how the hell do you do that i ahve been trying for 3 days now and can't figure it out i have adobe photoshop can you do that with it. If not then wat program so i use.

Thanx,
