So it’s not worth posting either on here on via the recommended link?

I realise the size does not equate to quality, but if the system rejects an image due to size you have to reduce the quality to meet the system’s requirements.

I believe my first attempts were with a cropped image which didn’t include the interface and required time stamp, but as it isn’t kept, even if only for a short time, how would anyone know?

As it only asks for episode, perhaps it doesn’t need the series at all?
