Just searching for some architectural images for a client and came across this,

Mayang's Free Texture Library Definitely going to be buying the DVD at some point.

Holy smokes. I've seen people give away a handful of decent textures, but 3800? This is a really great resource, thanks!

Pretty nice images! These are some good resources in the future. Thanks Chris!

Here's a few more free texture image resources:

Not as many here, but a good collection:

@ Chris, thank you so much for sharing, that's pretty nice of Magtag to allow you download 20 textures a day for free or an option to pay for the 3800. I am alway looking for decent buildings or texture.

@LadynRed, thank you also for sharing, great links!

Very much appreciative, thank you both! I bookmarked all the links.
