"Photo reading credits are used up. Contact the person who manages the service."

Where: Import students screen (/students/import), after Take a photo or Choose an image.

Why: the OpenRouter account used to read photos has no credits left or has reached its budget. The photo was not sent to the model.

What to do: contact the person who manages the service to top up the credits or raise the budget. Meanwhile, import the list from a .xlsx or .csv file. The photo reading option can stay enabled: the message will appear again while the credits are used up.
