Hey its my first time posting and I am having some difficulties with an image lets say I’ll upload a brick picture for a wall but it looks like it stretches the image greatly and if tried making multiple repeats of it but nothing works please help
use the Size controls on the Texture Map Input panel to correct stretching. see http://mediawiki.blender.org/index.php/Manual/Map_Input

I also find that things are easer if you make sure your texture images are square, that is, they are the same number of pixels wide as they are high.
