Texture.everflow.com is a free texture resource for artists and designers. The textures are geared mostly towards the 3d artist/compositor in mind. I am looking for support from the community, feel free to submit a texture, or submit a texture that you cleaned up/added an alpha channel etc.

If you would like to submit an image, feel free to attach it to an email to texture@everflow.com
Shortly, there will be browser based upload functionality.
