When I use a search I get no thumbnail results, just the blue tag links. If I click on the tag link for a particular image, it comes up fine.

Maybe a flux in our thumbnail server, do they show now?

No, I still can't see them.

I don't know then, since everything on our end is okay i have no way to debug this. Looks like a client issue to me.

GrapplerBot, what browser are you using? That might be a contributing factor.

It's happening on both Firefox and Chrome.

IE is not an option here.
