HELP Please

[boccia]

Good morning to all. As a beginner I have updated my website version of Phoca Gallery from version 2.8 to 2.8.1. The update was good, but I realized, go to the site, which has created a problem displaying preview images. The problem is that the images are arranged in a proper way, but if you hover your mouse over the photo triggers an effect that moves the miniature of 3-2 positions to the right, which also extends to the same page previews. I tried to read in the forum if someone had already encountered this error, but I have not found nulla.Mi can you help please?

Thank you all for your cooperation
