I installed "Recent Views" module on my site (www.best4future.com). I noticed that when I put the mouse over the small image under the sidebox "Recently viewed", there is no pop-up medium image. And all the titles for small images are "100".

While I I put the mouse over the small image under the sidebox "New Products", the medium images pop up.

Why is that? Is there any way to fix? Thank you!!
