Nobody can see your gallery to comment. The gallery you see here is with vb3 and might look different than say one that is a standalone or integrated with vb4. I would need to see your site to see what your talking about.
The vb3 postbit to my knowledge was a vertical td that contained user info on a post and we may use that in vb3.
I beleive in vb4 if I look at my posts vb4 uses a horizontal line to contain the user info and this is how we do it in that integration
