I know this message is a bit late, but look for the upcoming version
of the Alagad Image Component. This will add the ability to work with
images via urls just exactly as requested.

You can load an image into a BufferedImage (the Java class that
undoubtedly backs the image.cfc you mentioned) from an arbitrary URL.
Not sure the exact syntax, but a glimpse inside image.cfc and a
browser with javadocs should get you started.

Have you considered using _javascript_ for the job? You can create a new image
object out of the url entered by the user, then you read the dimensions out
of it

Have you considered using _javascript_ for the job? You can create a new image
object out of the url entered by the user, then you read the dimensions out
of it
So, I've seen the image cfc that allows you to determine image size
(among other things), but those images have to be local files.
Is there anyway to retrieve an image via a URL and determine it's size
WITHOUT reading the file in from the local file system? I would just
like to avoid a bunch
