Re: Image uploads

This may be a repost, I may have accidently sent a previous reply before I
finished typing. :)

Anyway, I missed the original point of your question in my earlier reply.
Unfortunately (& fortunately), you aren't being thick-witted at all-- the
API is simply that limited :(

In your shoes, I would definitely check out the Java2D-Image I/O API at:
http://developer.java.sun.com/developer/earlyAccess/imageio/

Basically, it offers you a quicker/simpler route to producing a
BufferedImage, which has the simplified getHeight() and getWidth() methods
you're interested in.

In code, it would go something like this:

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

HTH,
Levi
