I use the following construct to avoid the "?" in the url which stops the 
image being cached...
img src="http://www.domain.com.au/buttons/image.gif-System-3-ffffff-9-L/test";

then have a rewrite rule that redirects anything at /buttons/ to index.php
This way I can send file name of the background image, font, size, colour, 
offset,alignment and finaly the text to use.  and it is still cacheable.
If you want a copy of my index.php which unscrambles that lot let me know...
