Online image resizer

Ever needed to resize an image and didn't want to open a whole picture editing program just to do that? Well, why not use ResizR? On their own words:

Often you do not need more than just resizing an image on the fly. Before ResizR you required a desktop software to do this - heavy applications which can do much more than just resizing an image. ResizR changes the game - it's much easier. Select an image - choose the width - rotate optionally.
