Also about "fill the entire background so that there is no, to little tiling" - note that there are different screen sizes, different zoom definitions, and even different proportions between the width and the height of the screen/window. Therefore, it's not possible to create an image that will fit exactly to everyone's screen. If the image fits a certain proportion, then it won't fit another proportion, and it will must be either cropped, streched, tiled, or fitted in without filling the entire size.
