Many, many years ago before custom iframes were supported, CyTube supported queuing imgur albums by URL, which would then embed an iframe using a predetermined URL pattern.
It seems like that no longer works correctly (I tested it to be sure), and nobody ever uses that anyways (I checked recent logs, the only examples within the past year I could find appear not to have been intentional usages of the feature but rather were trying to add a specific image). Best to just remove it and if there is an up to date embed code for imgur people can just use the iframe feature now.
