Yes, you see the images back on the wiki. Apparently, there is alot with "broken(red)" image links still.

So what should you do when you come up to one which appears to have "broken(red)" image links? Edit the page and simply click "save page". The images will come back up to normal.

Here are the ones I fixed so far:
Enemies (except The Swarm series since it's locked by Equi. includes bosses)
Helmets Page (including all helmet pages. this includes all costumes too.)
Shields Page (including all shield pages)
Armor Page (including all armor pages. this includes all costumes too.)
Trinket Page (including all trinket pages)
Swords Page (including all sword pages)
Bombs Page (including all bomb pages)
Handguns Page (including all handgun pages)
Accessories Page (including all accessory pages)
All individual material pages.
All dungeon levels.
Most NPC and Vendor pages.

Ones I came across that are "broken(red)" but can't edit:
Energy (can't edit since it's locked by Equi)

Now if you excuse me, I'm going to sleep X_X
