There is a "pathway error" that prevents directly uploading a file from a hard-drive like we used to be able to do.
I think you can still possibly use a link from a web-hosting site like photobucket, but I don't use those sites so I can't confirm.
I tried to upload a photo last week as a test and still no go.
After the pathway error is tries to send me back to the post but then is sends a an error message saying the post has already posted (even though it has not).
I think with all the forward progress and changes with the OC and other stuff going on with MB, the powers that be have basically left the forum as it is to die a slow death, save for the few die-hard clingers like us who still log on.
I can't really blame them, as the "gun talk" dies down several yeas ago as facebook groups lead the way for a more mainstream way to converse about subjects. For example, the most viewed post over the last six months on here is the one about what we've been eating lately.
In a nutshell, facebook, tweeter, and instagram has beaten down and almost killed off the old-style forums.
Sucks.
