Honestly, I liked the infoboxes with the two tabs. I think it's fine to keep them that way.

Majority wins, though :P

Why? I like it too, because it's different from Stage48 wiki

I check everyday and saw a number of edits putting the pictures on the infoboxes back on the gallery.

I follow many pages too, and I honestly didn't notice that there was many of the edits that you're describing. Were the edits all by one user, or did multiple people try to change the infoboxes? In any case, I personally still prefer the infoboxes as they were previously designed.

Double images looks nice.

Try use toggle instead of tab.

This looks like something similar being used on Hello! Project Wiki, but we ended up creating a template that makes it easy to put in without using the tabber feature. I could probably move it over here.

I'll try Toggle right away. :P

if something like that exist in another Wiki, then I'll really stop using that... sorry. :P I just had a bad memory about someone deleting pages here that remind them of a wiki they like.
