This is driving me insane!

Running Firefox v3.6.8, Opanda IExif v2.3 w/plugin and I simply cannot get any photos on the net to show any EXIF data, even ones I know have the data.

Google doesn't bring up anyone with the same problem; the only cases I've seen have been people that have installed Opanda IExif but not the Firefox plug-in. I've installed and re-installed the plugin several times, but I simply do not get the EXIF option when I right-click on a photo. I've even tried dragging the picture into the IExif application, but it always shows "No EXIF data available".

Anyone else had this problem? Any ideas?

I know there are other EXIF plugins available for Firefox, but I want to know why this isn't working, and/or why I'm seemingly the only one on the planet who can't get it working!!!
