If you're using the Java platform, you can use ImageIO to read the image, then use getHeight and getWidth on the BufferedImage returned from the read operation.

I admit this is quite a heavyweight approach, so I'm sure there is an even better approach. I just have to find it. :-P

As for .NET, I have no idea. :-)

I've done this by execing the Image Magick "identify" command.

Easy enough if you're using Unix - although I think it runs on Windows too.

I doubt you can do it client-side.
