Dear David;
Ah, well, c’est la vie, I guess. Yes, the issue is resolved – at least now I have a better idea of what was breaking and hopefully work around it.
Again, great plugin. If I may suggest adding a line or two to your FAQ stating that overly large files (I assume that you are using Google Viewer to preview anything WordPress itself can’t handle) will not have a dynamically-generated thumbnail. Not that, given a year between this issue cropping up again, it would seem people are encountering the issue often.
Thank you for taking the time, and have a good week(end) ahead.
Regards,
Greg
