It happens often that people try to upload multiple images in their post editor at once. If they see a few successfully loaded photos and accidentally don’t check that ALL of them have been uploaded, the post ends up containing something like this:
It is counter-intuitive in that it is not clear why an image gets converted to a link…
Proposed solution - quick: disable submitting a post while there is at least one image which is still being uploaded.
Alternatively, it would be helpful to at least automatically remove those [Uploading...]() entries of not fully uploaded images from a post. Note: the actual text inside the brackets to check while removing from the post should be internationalized.
