As Administrator, when trying to update the profile for a classmate who just joined the website I wanted to upload a Master Photo. The first time I did it, it seemed to work as expected. However, the photo did not look good which I thought might be because the resolution was too low. Therefore, I removed the originally uploaded photo and tried to do it again but that failed. It appears that the upload process is functioning but there is nothing listed when it completes.

It seems to be behaving as if removal applies to every subsequent photo for the subject user.
