I usually don't respond to threads like this but I'm not sure why mebronx2000 got so much grief for his troubles.
Is the artwork his own creation? Probably not but I doubt the people he bought them from had the rights to them in the first place. I mean we take characters from different games and make artwork ourselves but do we own the rights to them and be able to charge people? I thought we were paying for the time it took to put them together and stuff.
There was someone here trying to sell the street fighter control panel art that was created from Martijn and rightfully so everyone was upset that he was trying to sell it but Malenko was gracious enough to re-create it, allow us to download it and show us how to do it ourselves
I've bought my share of artwork from people and have had people ask not to resell it and I was happy not to.
Just my two cents.
