Hi itsjustme,
Thanks for helping to alert us to this problem. We did experience a technical issue for about 5 minutes around when you started this thread in which several users received errors of this nature when uploading images, so I believe the errors you encountered were a result of this issue and that you will no longer receive them with future uploads.
If you do continue to receive these errors when uploading images, please contact our customer support team to let us know by mousing over the “Help” tab within your account and selecting the “File Support Case” option.
-Mike
