One way to use textures is if you have a program like photoshop or paint.net [which is free], add them as a layer over your picture. From there you can edit the properties in order to give your picture a cool and unique look!
I be takin' your textures. And commentin' as per your request. They're wonderfully amazing and I couldn't help myself even though I don't know the first thing about using textures... EHH. Thank you for these lovelies, anyhow! Yay!
