Wow, that was easy. Created an account over at Box.net and loaded up 4 free texture packs. Yes free for personal and commercial use. Box.net has a very user-friendly and simple way to load files and make them available for sharing. (note I also added their widget to my sidebar). So if you want some free textures, here are the links to all 4 packs. When you click the links you will be directed to Box.net to download the files. Enjoy! Please provide feedback. The only thing I ask is that if you use my images, please link back to me here and also visit my t-shirt store at Check it!.
This is just a thumbnail preview from the 4 texture packs. All 4 packs contain a total of 45 images.
