No, the thumbnails haven't been showing in my album for the last 9 pics going back about a year. It only shows the file name as a link. I uploaded a screen cap to show the issue. Not sure what the glitch was, but the screen cap seems to be showing normally so it must be fixed now.
OK- I see what you are talking about. The new image thumb is there. Most likely a thumbnail was not created for the other ones. Ultimately the issue that caused the site outage we have tracked back to starting before Dec 2016.. so that makes sense. Not sure if I can auto create thumbs. I'll try. I bet if you re-upload the thumb would be created. Thanks for letting me know this.
