Often when visiting listing pages (not always), the pictures are not shown. After a reload of that page the pictures show again. Pictures look good in lists (miniatures) but on the listing pages they are only shown sometimes.
I have disabled all caching plugins to rule out such a cause.
This seems to be a new issue, I have not seen it during the last years.
Steps to reproduce
Visit different listings
Sometimes the pictures will not show
A reload of the page will show the pictures
Actual result
Pictures on listing pages not always shown
Expected result
Pictures should always be shown directly when visiting a listing page
