No it advises me that the image still exists and checking it I see that it is not attached to anyone. The FAQ says "This disconnects the image from any profile, but it will still exist in the database for a short period of time so that it can be recovered. This way photos can't be maliciously or mistakenly deleted." I guess I will have to wait for the recovery period to expire. I am using Linux which allows characters in filenames which other operating systems don't allow so I will rename the file to remove possible problem characters like () and , so the upload goes smoothly in due course. I notice WikiTree did rename my upload so maybe the characters in the original file name did not matter but I won't take chances next upload.
