if you use images.google.com's 'Search by image' (click on the camera which shows us in the search box) function, whenever you post an image in the OT.com forums it puts an extra box next to the posted image.
(I edited a few times that's why there are three) Can try deleting them after you've taken a look, Jay.
Still not sure how this is done.
I think we need to know exactly what you do when this happens.

Here's the Firefox extension addon page:
https://addons.mozilla.org/en-US/firefox/addon/search-by-image-by-google/
The image.google.com function looks through the page and inserts it's own additional code whenever it finds an image. A 'camera' icon 
(which is my guess what the boxes are) on the found images, which when clicked auto sends you to google's image search. So when the 'insert/edit picture' function is invoked, the new code is found and the i.g.c extension does it's thing.
This is a test...........
I installed Firefox, and the extension.
I still don't know how you manage to do it.

After you installed the plugin, on non-google pages when you scroll over an image does that blue camera icon show up?
If no, then maybe the application is not activated. It started happening to me after I used the function for quite a bit. Seems that after I restart the browser the application goes dormant, so this problem most likely won't occur too often.
That little camera shows up on every image I mouse-over, no matter what site I'm visiting.

Ok, as you don't have the problem and I don't have the issue anymore, then maybe the problem got solved with the cache reload related to all the HTML code showing up recently.
Worked for me just several days ago, now that camera icon won't show up, nor works google's own Firefox plugin. Found Opera users with similar issue.
