I just uploaded and shared 848 free textures, free ones are scaled down to 1.500 x 1.000px, but when you register you’ll get 50 credits for original jpeg files coming from 20Mpx camera. Use it how you want - for example you can use it to create your own material or for project for sale. But you are not allowed to sell those textures on other sites and/or pretend to be an author of them.
They are no tiled yet, but if I find time I will create some full materials for Blender using them. Just need some time to collect more and pick-up the best ones for you.
