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
for ongoing cleanup projects.
That's an interesting idea. Every trope (and trope subpage) with an image should be linked on Image Source, and that page should indent that trope under the work, so any image from a redlinked work should be listed there.
But if the image is on the imagelinks subpage, I think we're out of luck. Link to TRS threads in project mode here.
You can always consult the Image Source subpages and spot the red links or absent links for the works.
Do we have some sort of list for images that pothole to pages that don’t exist?
