Custom Tileset in the Graal Editor

[lyrael]

Noobish question no. 2 - How do you get the Graal Editor to recognize/use a custom tileset?

I've used the type1.png from the tutorials section of this forum and created an entire new tileset using that...but I can't figure how to get the editor to recognize it so I can actually create a level with it.

Any help would be greatly appreciated.

Thanks!
