Collagerator

If you have thousands of photos on your computer that you'd like to share with your friends, there's a very simple way to send a lot of pictures at once: create a collage.

Collagerator is a simple app that lets you create photo compositions by making a mural with a lot of photos in just a few steps. Want to make a poster with all the photos you've collected of your friends? No problem. Just run the program, choose the measurements of your poster page, and select all the photos you want to appear in your creation.

Once that's done, Collagerator places the pictures automatically, but you can move them around as desired, enlarge, shrink, or rotate them, or superimpose some atop others. And you can also add frames to your photos and choose the type of background you want for your collage.

Another good feature of this program is that it adapts your collages to different formats, from a sheet of A4 paper to the screen of an iPhone or iPad.

In short, this tool is very useful for those who need to create something decent in a few minutes and don't want to bother with complicated design tools such as Photoshop.
