I have a jcarousel plugin for Magento that shows featured products. When you hover over the image it displays a bigger version of the image. In that bigger version there is an
* (asteriks) in the top-left corner.
It's sort of hard to explain, you can see it in action on http://www.dooor.nl/ when you hover over the caroussel in the middle of the page (above the newsletters, below the moving slider).
I don't know how it got there, it's not in the original plugin. Problem is that I can't access it with firebug to see where its coming from since I can't select hovered images.
Edit: Here is the original plugin: http://www.hellothemes.com/demo/?theme=hellowear. You can see there there is no asteriks.
