Probably not, because it doesn't make much sense. The whole idea of the game/the menus/the manialinks is that it looks the same, whatever your resolution is. This is why quad size are always relative to the screen size. For good display results, you should use quad size "about the actual size of the image" (ie. don't use 1024*1024 images to make icons that are sizen="5 5") ; but you have some latitude here, so don't worry too much about that. Just make clean images (eg. JPGs should have a good quality).
If you really need an image to be displayable at many different sizen's, consider using DDS textures with mipmapping. It's only relevant if you want to use, for example, the same image for quads sizen="5 5" and sizen="100 100".
