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.
If they're tasteful, I think they're fine (would need to check on that applying to examples); just don't link the work.
Same applies to the images. In fact, IP's introductory thread contains a list of trope pages with images from works that can't have a page due to P5 concerns. These trope pages will also have a hidden comment noting it.

Something I'm not sure about is the status of examples from Hentai works. I know that they're strictly disallowed on pages like the Nightmare Fuel page for video games and Nausea Fuel page for Anime, but what about singular examples on trope pages, like Everythings Better With Dinosaurs ?
