As this web site is not just about stock textures but free royalty-free images in general, today I picked some still-life photos of books. Actually, properly cropped they are easily usable as backgrounds (and the third looks even good as a desktop background). The books in these photos are quite old, btw., which makes their colors and textures even more interesting. If I see that you like them (some stuff here gets downloaded quite a bit - thanks to everybody who sent a link!) I will take and post some more images like that. A little reminder: Use the stock photos posted here freely in your design projects, blogs and web sites, but please, don´t re-distribute the images as such. Beside that, enjoy the material provided here and feed your design ideas.
