I'm sorry to hear about the difficulties you have been experiencing. We have received a few reports of image uploading difficulties this morning, but we have not been able to find anything amiss on our end that would explain why you may have started to encounter these uploading failures to this point.
We will continue to monitor out image uploading service for potential problems though and I will keep you posted if we are able to uncover any possible solutions for this issue.
Based on what you have described, it sounds like this issue could be a result of a connection problem between you are our image hosting service and I just requested some information from you through your open support case that will help us evaluate that possibility.
We appreciate you taking the time to bring this to our attention.
