Indeed. The method can return a BitmapImage instance, which may contain several bitmaps of different size. In the Haiku port, I've temporarily made some useful BitmapImage methods public, to iterate over all images contained in the object and find the one with the size I want (in the browser code later on). Is there a better way to do this? How do other browser projects handle this? Would a patch to make some BitmapImage methods public have good chances of being accepted or is there another vision?
