While well-intentioned and very kind, what you're doing could be perceived badly by the person who made the textures you're using and now distributing for free. You can use those textures as much as you like, but the designer of those textures would have a reasonable gripe against you distributing them to since they'd probably prefer that they get paid the (really very reasonable) $4 per person who makes use of their work. Maybe consider not distributing the files anymore, and possibly give a tutorial on how to do what you did instead?
If you've already gotten the texture from Lord Dragon, consider doing the right thing and pay the designer their four bucks for a product well made: http://www.rpgnow.co...Base-Trench-Run
I'm not trying to make anyone feel bad or ruin anyone's fun, but if I had spent the time making that stuff and then saw someone giving it away for free I would be unhappy about it, and figured I'd chime in on their behalf.
