I had my cusin build a site layout for me with adobe photoshop but i want some changes made to but he's been to busy over the past few weeks to do it. I have photoshop installed but i have no clue really of how to use it, it's a window image of the site and inside of the window he placed a pic of a kitchen. Instead of the kitchen i would like to place a pic of a school bus but don't know how to do it, can some help me?
