Reputation Image Values?

[Angry_Sun]

Hey guys, I need some help with my reputation system.

I'm looking for some way so that, here look at this:

Grey = 0
Red = -X
Green Image = 1 Rep point
Light Green Image = 5 Green Images [Or 5 points]
Yellow Image = 5 Light Green Images [Or 25 points]
Blue Image [the max] = 5 Yellow Images

The images will replace each other one the next step is met. So if I have 4 rep points, I have 4 green images. But say someone gives me one more rep, the green ones disappear, and instead I get a light green image. Say I get one more rep, I have one light green, followed by a green.

And the organization will be from highest to lowest, left to right, according to image value.

Anyone able to do this? Or help me do it?
