Whow, sounds interesting. But how can I "open" the file (in ASP) ?
And does it also work with JPG and other image file types?...

I'd like to obtain an image's width and height. I find interesting articles on several sites... However, all these scripts only work with images that are stored locally.

Can you give any hint on how to do the same thing with images that are located on external sources?

For example, I mean, how can I obtain the width and height of this image: http://www.heartofwisd om.com/images/blog/Stumbleupon/thumbs-up.gif
