How to texturize?

Ok, somewhat new to blender. I ask for help on how to put a picture into/onto a cube in blender so it looks like a crate/box, and people send me links. Its a school laptop so i cant watch video’s and most links are bad. Please someone help me. Thanks -Jolly Green Giant

Most tuts these days are going to be video tuts.

There are a series of PDF texturing tutorials, but I HATE the way he teaches texturing.
