When I try to upload an image to the Community Generated Content section it shows up as only "image url" and the "choose file" option is missing. This happened when the categories changed.
The only way I could upload an image is by creating a draft in another category like General Discussion, upload an image, copy the url, go back to community generated content, and paste the url in the new post.
You can’t post images in most categories, Zeni decided on forum launch in 2013 that they don’t want to be in the image storage and indexing business for their forums, which isn’t uncommon. There are a few exceptions, but for the most part we’ve always had to upload photos and videos to a 3rd party hosting site and link them in posts and comments here. This isn’t new.
