Photovisi, is a new free web based service that lets you create photo collages.
It is easy to use. You first select a collage template, then add your photos and after dragging photos around you can download the collage.
They have a print on demand service so you can get it printed out the top link allows you to down load the image and I thought printed out on a home printer they would make nice home made gift wrap for small gifts. I have mine currently used at a desktop.
As you can see from the screenshot, it’s a fun toy anyway!
