I need help compiling some sprite sheets

Hey guys, I am trying to create sprite-sheets for some characters developed for a game PARPG. Specifically, they can be found here:

http://subversion.assembla.com/svn/parpg-assets/trunk/objects/agents/npcs/

 

I intend on uploading the ordered sprite-sheets under the same license after.

They isolate each frame into an individual image, and then each image corresponding to a given direction is further isolated into it's respective (direction) folder.

I am using a tool to merge these images but it doesnt' keep the images in any particular order, so I can get some seriously non-sensical animations. I spent three hours going through the tedious process of importing one and the animations didn't even come out in order ...

Any advice?

 

Thanks.
