Have a question about how the TVTropes wiki works? No one knows this community better than the people in it, so ask away! Ask the Tropers is the page you come to when you have a question burning in your brain and the support pages didn't help.
It's not for everything, though. For a list of all the resources for your questions, click here. You can also go to this Directory thread

I made a previous ATT query
about the user that made that page, Yoshi Fan Boy 43, and it seems he abandoned all activity after MacronNotes' message instead of fixing their mess. Since there's effectively no pictures anyway, I presume it's fine to just place proper pictures if you want to make the effort, or just delete the hotlinks.
Yeah it's fine to fix the images yourself or just remove the hotlinks. You don't need a thread for that.
Macron's notes

Pokemon Mystery Tourney is filled with hotlinked images, which don't show up properly if they're not put into the image uploader first. What do I do with them? Do I replace them all with proper images myself or do I have to start an Image Pickin thread first?
