Top 10 free textures websites

There are plenty of websites on the internet that offer free textures. However, browsing through 40-50 sites to find a certain texture can prove to be a time consuming task. With that in mind, I have made a selection of 10 websites which I thought may be useful to you too.
Probably the most notorious site where you can find tons of free textures of various categories.
One of the oldest textures sites on the internet.
A very comprehensive site where you can find tons of marble and stones textures.
Probably the best site for free people cutouts; each file comes in psd format so you can easily composite it on your rendering.
A great site for marble textures. Registration is required.
Several categories, but I especially like the grunge textures.
A nice collection of textures and a set of trees cutouts.
Several types of wood textures
Most of the textures available from this site require additional work in order to make them tileable, but the resolution and the sharpness are great.
Another great site with large variety of textures.

Again, this isn’t meant to be the most comprehensive list, but if you think that I have missed something important, feel free to post a link in the comments section.
