html image rotation

I need to be able to rotate html content to landscape or just rotate 90 degrees.
What we need is to find some attribute that goes into the <IMG>
tag in an HTML file. For example if their exists some kind of
ROTATION attribute where you could specify either an angle
or perhaps "Landscape" or "Portrait" mode. For example,
if there was something like:

<IMG SRC="test.gif" ROTATION=45>

The other option would be finding a JavaScript which
rotates the image. Although I do not know yet if the
HTMLVIEW control class on WinCE v2.11 supports
JavaScript or not.
Thanks,
Bill
