I want to show my pixels in the order pixels area

I will try to explain: I have filled my homepage now with some picturelinks (I "bought" the pixels myself). Everyone knows you first upload the disered picture and then you "place" it onto the grid wherever you want if there is a free place. Then you pay. But when you are placing the picture, all the already token places are shown as red. I want to show the original homepage grid in stead of this. To make it more clear, I want my customers to see the already placed advertisements in stead of the red blocks. This is vital as I devided my grid into categories with self uploaded images so they will see the categories when they order. Anyone knows how to do this?
