Hello Barrie -
Apologies for the delayed response.
There was an issue yesterday that came up regarding the Image Management area of accounts which was widespread. Our engineers were able to resolve the issue yesterday afternoon and that area of accounts is operating normally again. You should have been able to resume your usual activity at that time and it sounds like you were able to do so.
Should you encounter further difficulty, please don't hesitate to file a support case from under the Help tab of the site letting us know the details. Please include either a screenshot or the full text of any error message if you encounter one so we can investigate further.
Apologies for the inconvenience this has caused.
