Upload an image

oh, that time I guess it finally timed out and I didn’t have to end task. after being unresponsive for probably 15m or more (however long it took me to document/screenshot/etc and write up bug) it finally gave me a
”failed to upload files” or something dialog and returned control to me.
If it happens again, I’ll get a screenshot of the dialog.

here we go again. I guess I’ll go make a sandwich and let you know what that error says when it un-hangs
