At the moment [[image:clear1x1.gif|50x333px]] or [[image:clear1x1.gif|50%px]] and similar versions are all accepted, but their effect is always 50px. Changing the aspect ratio is usaually a bad idea, so that's no issue. But a width as percent could be nice: Web design with absolute widths is very 1998. My browser is older and supports percent.
Percentage would be tightly coupled to the source image's pixel size, which makes it very poor for portable code. Size can vary dramatically from image to image, and could be changed over time for a single image (eg, uploading a higher-resolution version).
