This is a free, quick and easy to use photo collage maker for your PC or Mac.
It lets you create and save photo collages - i. e. pictures composed of many smaller photos arranged on a chessboard pattern layout.
The application automatically loads, resizes, clips and arranges dozens or hundreds of pictures for you, so you can produce a collage within minutes, what would take you hours if you did it "by hand".
Save the collage as a JPG or PNG file, and do what you want with it: print it...
