I'm not staff, I'm not fixing anything. I merely note some of the changes, repeat previous observings and offer my (limited) insights. If you think decorating your content with images is visually appealing, go ahead, it's your wiki. Though staff occasionally replies here, they rarely address individual issues here. For that, you'd best send a contact form, though it should be noted they're off for the Christmas and New Year tomorrow so you probably won't get a reply.

Preview works, it just doesn't take the right rail into account. Or display the categories used, or update templates that have since changed. This incorrect width has been noted before; it also did not have the right width on Legacy but less pronounced. It's probably been reported enough already that they're working on a fix, but an extra report couldn't hurt.
