[thespirit]

Everywere i see the on the forum the topic icons is a separate "box" like in this thread were the green arrow is in front of the thread, but at my forum it is not in a separate box......

but i need it in a sepparate box because i want to change the post icon with a previeuw image of the picture in the thread, if i do that and it is not in the box it dont look good, you get this:

i need it in a box like this:

see pic 3

i allready figured out how to get a differrent picture before each topic ( making 2 more topic icon catagorys and make 1 of them not usable for all and move the icons there after i added them) but they need in a box .
ps in default style it is the same, no box.

see pic 4

How do i get the box back to put the topic icon in?
