I got a simple solution for finding good transparent images of weapons. All you need is 1. Find a model you like in CS 1.6 or CZ skins section. 2. Open it in a model viewer, for instance P2 model viewer. 3. Make a screenshot. It will be saved as a perfect transparent .bmp file. Crop, convert, ready! :)
I hope you'll find time to replace worse images. I've mentioned some issues below. In addition, I don't find the current AK good.
In general, the new pics are good but I do not like several things: - the scope on scout (it's too far to be useable) - the magazine on mac10 is too long (goes beyond the buy pic borders) - P90 looks different from the style of other pictures (it's turned a bit at the viewer, while the rest are displayed flat). - tmp and HE are too dark (they merge with the background) Still good work!
