How to Create Border on Thumbnails?

[Vibhor]

Hi,

First of all, thanks for releasing such a great gallery plug-in. I am using it since last year, and everything is working like a charm. Though, today I have a question related to a slight modification. So, here it goes: How do I add border on thumbnails which appear in a box below navbar, on forumhome?

Hope this screen shot would make the question more understandable:

Thanks!
