Anyone have good textures?

[RadicalOne]

I need textures that are color-shiftable, tileable, and free.  Does anyone have any?
Before anyone suggests, yes, I have searched google images. I get poor results when I do.

Here is a few sites:
CG Tgtextures
Mayang's Textures Library
Arroway (Does sell texture cd's, but have previews on the site that works well in size for bats)
Animax
Image*After
Free Seamless Textures

Two texture programs:
MapZone
ImageSynth
