Rated 5 out of 5 stars

Great tool - thank a lot :-)
It would be great, if you could add the standard picture infos (like resolution, resized resolution, filesize) that firefox shows in its "grafic-info" dailog.

So I would not have to open two windows to get all infos for a picture. I would love you for that ;-)

This review is for a previous version of the add-on (0.4). 

I guess you're talking about using FxIF on Firefox >= 3.6 since in earlier versions and SeaMonkey it's embedded in the Properties dialogue anyways.

If I'm right, you might want to install Element Properties (https://addons.mozilla.org/de/firefox/addon/14228) with which FxIF cooperates well.
Else I'd appreciate more information on your environment and what you request.
