I've successfully installed and used piwigo for some time but recently started uploading a larger image size. The average size is still only around 200kb but I'm finding that the thumbnails and larger image do no always display. Instead I get a triangle with an exclamation mark. To resolve the issue I refresh the page and the images display. It is not necessarily consistent for a particular photo which leads me to believe that it is a timing problem.
It's worth noting that the thumbnails always display in the album and the problem only occurs after selecting a thumbnail and navigating from there. In the attached screen grab, the images will be displayed if I refresh the page.
Has this issue occurred to others?
Is there a setting that can be adjusted to increase the time to load an image before displaying the error?
Using a different browser doesn't affect the problem.
Once the image has been cached the likely occurrence of the problem is reduced but not necessarily resolved.
