creating a realistc wall help

A couple days ago I asked for some help with creating realistic walls for my game ,the effect I want to achieve is exactly as done in the Dalzasoft youtube tutorials-https://www.youtube.com/watch?v=tp_S2Q4oQwU-the problem is I access the net from my celphone and when I download their video I can hardly see what’s happening and there’s no comentary

Can someone please help a noob out by breaking down that video tutorial step by step

if you are using blender 2.5. it has an addon by the name of “Images as planes” enable it , and import any wall texture, it will turn out as described in video.

basically, it loads up a texture on to a plane, with normal map.
