This script reads a series of images and creates one single output image you can use as a tiled texture, e.g. in the Blender Game Engine.
Set 'Tiles X' and 'Tiles Y' to the number of tiles you want.
Set 'Source' to the name of the first image in the sequence, the others will be loaded automatically.
You will be notified if there's a gap in the sequence of numbers and the script cannot continue.

### changelog ###
# 20060103 v1: release
# 20060104 v1.1: improved foolproofness :)
# now it' hard to do anything wrong:
# -all you have to do is set the number of tiles and the name of the first image in sequence
# -images are searched automatically (numbering and extension)
# -size is set automatically
# 20060122 v1.2: 'bug'fix
# Image.save() always saves targa, so I check the filename and change the extension if it's not tga
