Issue

  • Our team recently noticed that they can't use PNG files anymore and can reproduce it by:
  1. Upload PNG file to Documents and Media library (please note that after page refresh Liferay does not show an image preview)
  2. Go to any Content Page and click Edit
  3. Drag and drop and image Fragment and double click on it to select an image
  4. Observe the previously uploaded PNG file is not visible on the list

Environment

  • 2024.Q1

Resolution

  • It is not visible mostly likely because the file extension was manually changed and this would also explain why the preview broke as well. 
  • Now if your team often needs to manually change file extensions you likely need to implement a service like Imagemagick
