Thanks Kris, I don't really understand how this function works :s maybe you can explain me. The param bounds is the bbox of the requested tiles isn't it? And var bbox is the map Extent ?
My problem is to find the good number of tile to return. My tile are like this 1 2 3 4 5 6 7 8 .... The bbox and bounds are in WGS84 and my images have no projection it's just images. Thanks for your help.
