Image Creation:

A third document exists, titled "SSgfx." Open it via Notepad and you can put in your own images:
[X.tga] - Replace X with your image's name. Images must be transparent and in TGA format.
V W,X,Y,Z - Replace V with what you want SSwep to be able to recognize in "sprite" form.
W, X, Y, & Z deal with the weapon's dimension limits, pixel-wise.
The best and safest number pattern is "1,1,32,16."
