MasterNu,
Here is that link.
The script works really well in Photoshop.
The first thing I do is use the built in script that comes with Photoshop called Load files into Stack. In Photoshop click Files, Scripts, Load Files into stack.
This brings up a file folder dialog to load all of your mages into layers automatically. Just select all of your images off of your hardrive and use this script and they will all be loaded as layers into Photoshop. That's the first step...getting all of your images into Layers. Once in layers, you can delete the backgrounds, Trim to center your character etc.
Next you use the script found here to load all of your layers into a sheet.

Layertospirte.zip is the file, found at the bottom of the page. The author spelled it wrong. :)
Anyway...you'll need to save the script in Program Files, Adobe, Presets, Scripts unless you have photoshop in some other location. Then you will find the script in Photoshop under Files, Scripts.
Use Notepad to load the script so you can look at the code and make one simple change. Make sure you take Notepad off of only looking at .txt files or it won't see the script file.
Using Notepad, you can change one variable in the script in order to set the # of columns (across) you want in your sheet. Then run the script on your layers and watch it make your sheet automatically.
Very sweet and a huge huge time saver.
