When will this be supported? Will it ever be supported again? It really should be imo. It is INCREDIBLY frustrating (especially for newer posters) to see image uploading options available, but when you go to use them, nothing works.
As it stands right now, the only reliable way to post images/screenshots is to use a 3rd party site (imgur for example) and link to it instead. It works, but it's super unfortunate that the 'upload image' option that is right here on these forums is non-functional.
