This is very simple 4 photo wallpaper template based on smart-objects. It’s basic size is 1600×1200, but you can scale it down or up. Basic background is blue, but can be changed using the “HUE/SATURATION” adjustment layer.
This template is based on SMART-OBJECTS, so it needs the Photoshop CS2 or newer to work. Fully tested on Photoshop CS3 and CS4.
Changing the four images is as easy as opening and changing 4 smart-objects. If you are not familiar with smart-objects, it is simple and you will find description included in PDF file, or you can check the Photoshop’s help file.
