I have a jpeg image, and I want to work out if it is progressive, or not. Is this possible?
I've tried opening it in Photoshop, but couldn't find anywhere where it has this sort of information.
Any ideas?

Appreciate any help.

Good question. I tooled around a little with it, but I couldn't find any way to determine it in photoshop either.

ImageMagick ( has a nice tool called 'identify' ( that can be used to tell if an image is progressive.

from the command line:

identify -verbose FILENAME|grep -i interlace

if the result is anything but "none", then it is a progressive jpg. 'identify' can tell you all sorts of things about an image's encoding.

Thats good to know, I guess. You would think Photoshop would be able to do this too!
