I did used that texture at first but It was looking very bad when stretching it as background, so i decided to make it as repeating border and then fill with either random semaless tiles background or just with solid color.
only thing i need is to have texture that have only 30 pixels of "dirt" on edges and goes into solid color in center.
if center of the picture is too detailed then You can see many edges at page borders with center :/
Ohh I have an idea,
If You could edit that texture on edges so there is no so much visible "border" between then.
Browser to create container on Wikia will sample texture on edges and create any resolution page as needed so we can have containers of 300x200 pixels or 500x500 pixels etc. I know I could use picture as background BUT... it's only good when You work with high resolution pixtures because streatching not gonna be visible, in case where we have PixelArt we don't want to stretch pixels around so seamless to center texture is required :(...
