i wonder if i am the only one who has wondered about this, you know the way there are four pictures on the back of the planescape:torment box, well where is the picture with the modrons in it from? i have played the game litterally hundreds of times and have even written a walkthrough on it but i am still stumped, please tell me where this is as i only have the very first version of the game.

It's from the alpha version of the game heh.
You won't find it in the actual game.

alpha version? what? explain please...

Alpha is the pre-beta (obviously) stage of the game. Beta stage is the one reviewers get (like I did of BG II) to write a preview on.
Although alpha is a very early stage of the game which only the game developers and some lucky people in the industry get to see.
That's it.
And mostly the boxes are made quite some time before the game is complete so the pics you see on the boxes are usually different than the ones actually in the game.
