Re: Image uploads

Sorry, missed that part of the question-- Unfortunately, you're right on
track and retrieving width and height is really difficult with
java.awt.Image. :(

There is a better way though, I would investigate the new Java2D-Image I/O
API at:
http://developer.java.sun.com/developer/earlyAccess/imageio/

Basically, it will offer you a much cleaner route to creating a
BufferedImage.

BufferedImage bi = ImageIO.read( [File|ImageInputStream|InputStream|URL] );
getHeight()
