good tut on how to work with the latest built background images !

how do you disable an image ?

when you load let say 2 different front pictures
and need to select only one how do you disable one picture

i can reduce the opacity but when i go to side view i still see the front view one!

any good tut on this to clarify things

and what about a loaded image affecting the UV also ?
how does this work ?

happy 2.5
