Image links broken

[AdieB]

Ok this is not an Actinic issue (at least I think it isn't), but Google Merchant centre is giving the following data quality error.

The submitted images links are not working properly. Please ensure that you update your items with working images links

If you click the link the image loads fine. I have googled but have not found an acceptable solution.
I have deleted the Acatalog and refreshed the website.
Any ideas appreciated.

Those are all quite small images. Would your other images that are Ok be larger?
