I have a gallery of 30+ JPGs. For one of the pictures the thumbnail is not shown. Instead an icon and the title of the file is visible. IF I click on the icon then the JPG is shown normally. I renamed the file and changed it a little bit but it doesn’t help. The phenome is shown here: www.ti-cons.com/TC2/index.php/en/services-en/men-at-work-en It’s the last picture.
