Mosaic managers help their users to easily create personalized mosaic images, i.e. large images created by tiling other images together.
These apps will enable users to choose either the large image or select the folder containing the pictures to be used for creating a larger tiled image.
There are also a number of such tools that feature support for searching images over the Internet or on dedicated sites like flickr, Google Images or Facebook.
Additionally, users have the option to adjust the number and size of tiles they want to include.
