I have been looking for this far and near. I want the attached image to open in a popup window (no scroll bars, no resizeable) when clicking on the thumbnail instead of just a new window. I know how difficult it is to come up with something that will calculate the size of the image, but in my case all my images are the same size and are square, so that is not an issue. This site has it (http://www.bonsaitalk.com/)

Also, I want the thumbnails in my vBandvanced portal to link to the thread it came from (I have a different style, so it will only work in that specific section).
