I am having the exact same issue and wanted to add to this post, hopefully we’ll get some fix. Currently, the way the images display, Foogallery is completely unusable.
Please check under FooGallery Settings -> Images Tab -> Thumbnail JPEG Quality
Make sure it is 80 or 90 and click Save Changes.
This problem seemed to come about when upgrading from a previous version where the JPEG quality was incorrectly set to zero.
Forcing a save for this setting should fix the problem.
Please let me know otherwise
Just wanted to follow up. The setting that you mentioned already had “80” and produced the extremely pixelated thumbnails. I changed it to “90” and it is back to normal now. Thank you.
Quite right! I changed from 80 to 90 and has fixed the problem.
Thank you so much!
Greetings, María.
