LF-help with target and ToT frame editing in lua

[ak_mr_green]

What I would like to do is ADD an "image" into the lua (iguess>.<) of the oUF that i have choose'n/will choose to use, as my player/target/ToT frames.

I'd like this image to be behind the Hp/power bar frame of the target. ToT and Focus frame's. When you have nothing target'd there is no frame, but when you do, obviously the target "frame" pops up showing you the infomation about the target.
I would like my image to be attached to the back side of the target bar frame's i am useing/will create.

If anyone has used or try'd out spartanUI, I would like the frames to operate something close to that.

Here is a pic to try and help me describe it? O.o

The white circle'd frame's/bars are (close to) the bars i would like to use. But i would like them to have a border/background type image, like in the spartanUI taht is below them. The thing is, I want the border/background, that I add, to Not be there if I do NOT have a target. If i have a target tho, i want the bar frames to be displayed, overtop of "said" background image.




My PROBLEM!!!

I'm really new to all of this, and have been try'ing to educate myself the best i can but its rather..... intimidating,(lol, i cant spell either!)
I can make the image i want on my own, all fine and easy, but Actualy makeing the image work in the oUF with the target frame, just, confuse's me. I dont know If I'm asking in the right place, or if I'm even asking the right question!

TY for help if ANY is out there!
