This works if I delete the 1.png image from my server:

I think this was included in previous versions of ChurchCRM, but doesn't seem to be in the current codebase (deployments), so I don't think this really needs a code fix - people should just delete this image.

All other (supported) pathways for image uploads will ensure proper image format.
