*Sigh* My suggestion is for only allowing the posting of stuff that is on Gelbooru.
I am not asking for common image posting. I am asking for only be able to put on the comments, of the forum, stuff that is already uploaded to Gelbooru.

The comment by Jerl didn't sound like it was a definitive thing. That's why i did the suggestion.

It would be a nice thing to add but what would stop people from uploading 2000x2000 images in the forums? That would cover up an entire page!

Thumbnails.

Ah. What's stopping you from adding that function though?

I don't know PHP and I don't have access to the server.

Yea fair though it might be worthwhile to talk with your other workmates on here about trying out pictures on the forums if you're feeling up too giving it a shot. I bet it would be fun to try out something new on the forum though.

Even if you put it in the Trac it would be a low priority.

Is there an explanation somewhere that explains what Trac actually is and what it does?

A massive backlog of (mostly) update/feature requests for Gelbooru. You can request features you'd like to see on the site or report bugs by creating a ticket from the top of that page.

As I understand it they do not have the funding to pay someone to work on these requests on a regular basis, so even updates that seem relatively simple to code (like the one being discussed) may never see the light of day.
C'est la vie.
