I had taken these textures about one year and half ago. These would be very useful for CGpeople to employ them for their tasks. I did not do even an ounce of modification and enhancement on the images due to keeping them completely raw, and abandon them to your own desire. Thus I have abdicated modification-prior-to-post anymore.
Here you can download the brick textures stored in a RAR file.
and here you can have a snapshot of the three textures.
