Steps to reproduce
- upload images (.JPG), size differ from 2 MB to 15 MB
- open folder with images
Expected behaviour
Preview generated.
Actual behaviour
some previews are not generated, error shown in Image Viewer:
“Could not generate a preview of this file. Please go to the next slide while we remove this image from the slideshow”
I’m sure the files are there, because I can download them.
