Colorburned.com is giving away a handful of high quality textures at their website. Each set contains about 35 images which can be downloaded for free. Graphic artists and designers are increasingly turning to the internet to assemble components for their products, including using high resolution photography as background textures. Try layering these textures (lowering the opacity of the layer so it fades into the background without being distracting) to add depth to your images.
