Un-Tile Image

Hi,

Does anyone know of a program that will join a collection of image tiles together into a single image? The column-row position information is stored in the file name. I want to join the image tiles into a single large image.

Thanks
Jaycun

(PS. can gimp or photoshop cs2 do this?)

This Gimp script may do the trick:
