Last week I posted a collection of Photoshop brushes for creating your own textured graphics.
In addition to using brushes, you can get great results and save considerable amounts of time by taking advantage of textures that are freely available.
One excellent resource of textures (and other types of stock images) is Stock.xchng.
Below you’ll find more than 60 textures from their site. Each image links to the page on sxc.hu where the image can be downloaded.
