PhotoTiles

PhotoTiles creates a tiled photo of a folder of images, web page graphics, movie frames or PDF files pages of various dimensions and sizes.

When tiling images in a folder the program can also generate an HTML image map file. When tiling a PDF you have the option of creating tiles of images or as true PDF pages, one per "cell," in a single page PDF.
After the program is configured by specifying a few options, simply drag a folder of images (or movie file) onto the application, or its main window.
