Roll Over Images Getting Stuck

Hi, I used the Jroll plugin to allow my images to roll over. My images are also “clickable” and open up to a large format of the picture with a watermark, however whenever I click the back button to return to the original page the picture gets stuck in the secondary roll over image until I refresh the page. Any ideas?

I’m using the twnty ten 1.1 theme and the page in question is here:
