Subject: image dimensions
I have a file upload button, which seems to work fine. It'd be good
to know the image dimensions at some point in the process so I can
proportionately adjust it's size. If I can get the size when I
select the image which has been Browse-> selected from the hard
drive, or get it during the upload (CFFile) or at display time, I can
do some sort of "size containment", if it's too large at least.
