OK - just put the offending folder on Google Drive. There are no filters - just the jpegs as this is the folder that is the result of the "Create . . " command.
OK. Thanks. Did you email me the link to the Google Drive folder? I don't see it: even checked spam. The folder containing the 7 originals with filters would also be helpful: I really need to catch the problem when it happens. The resulting folder (the created JPEGs) might help but by that time, the problem has already occurred and the image headers have already been corrupted. Instead of email, you can PM me the Google Drive link(s) here if you like: that's probably easier.
Regards,
Mike
