Hi,
I reinstalled the image optimization module. I lost the backup, but I can live without it. I wanted the optimized images, they were already optimized. However, the newly reinstalled module did not know this, so I ran the optimization again and the module can not optimize beyond what was already optimized, and that's great because the images do not lose quality. This is almost a different way of getting to the same place if this bug had not happened.
Regards,
Eric
