Hi there!

Thanks for reaching out.

You can upload your screenshot on your online server or drive then share just the link with us. You may consider any online free tool either such as imgur, lightshot, etc.

Did you try to clear your Joomla and browser cache? Is there any error on your console? Which browser and your environment specifications with version numbers.

Please note that, with only screenshots it's really tough to guess the reason behind the issue.

If possible upload your site to a test server and share the access with us to check.

Best regards,

Hi

Thanks for contacting us and sorry for this inconvenience. Could you please give me a screenshot of your issue? You can use it for uploading screenshot.

this is the screenshot of my issue: https://www.bitland.eu/files/blur.jpg if I click on the thumbnail the original image is visible correctly

even the thumbnails in this gallery have the same image corruption problem https://www.bitland.eu/files/blur2.jpg

solved - I deleted the albums and rebuilt them, now the thumbnails are visible correctly
