preview of uploaded videos will fail to load #14
Description
it seems like imgur takes a while to process the video.
grabbing the url just after upload will result in a blank page. after a few seconds, the video plays ok.
submiting a video with a broken preview will also attach the video correctly to the post.
this tends to happen more often with longer/heavier videos.
maybe we should set a timeout on a succesful upload and try reattaching the src a few times?
