Can you make a tutorial for me? (on texturs)

Hi! Im new to Blender(and 3d).
I whant to apply differents textures on a polygon.
Example: the top face of a cube with a cloud textute, the bottom face with a rock texture etc…
My textures will be created in photoshop.
What is the best, most intelligent way and to do this?
Tanks to you pros!!!

Try this:

http://www.blender.org/modules/documentation/htmlI/x4272.html
for multiple materials on an object and this:

http://www.blender.org/modules/documentation/htmlI/c4431.html
for texture information

For an excellent resource that is shorter than the complete documentation, take a look at:
http://members.home.nl/dotblend/download.htm
and download the 3 parts.
