TilePhotos creates an array of sub-images of a given image. The tiling of a given image is determined by specifying the number of row and column subdivisions. Record these values in the Preferences window of the application.
Drop a file (or folder of images) onto the application icon in the Finder, or its main window to tile it. You will be prompted for a destination for the generated tiles. Each generated tile image will have a custom icon preview.
TilePhotos is available on the Mac App Store.
TilePhotos is also part of the Limit Point LLC Utilities Bundle: http://www.limit-point.com/Utilities.html. Purchase a Utilities password to activate all the utilities, including TilePhotos. Upgrades are free, new utilities are included.
TilePhotos initially runs for about ten days without a permanent password.
