Some sprites have such a huge gap there is no easy way to do it in the program. I will look into the extra period issue.
EDIT:
It seems it was my own mistake. I just never noticed the bug as Windows automatically removed the extra period.
v1.5
-Fixed an issue with additional period at the end of extensions.
-Added the starts of a tile cutter in the source (not available in the GUI yet).
I greatly appreciate the bug reports! Please continue to tell me about any bugs you find.
