After successfully making an installer for a qt application, I realize background images on qwidets doesn't show when installed on different computers although they do show on my own computer. I'm sure it has to be with dynamic libraries but i just don't know how to go about it. I need help please.

  • are the images correctly bundled? (as in the locations are not specific to your computer) Commented Sep 9, 2013 at 11:36
  • i compiled the images using the qresource compiler Commented Sep 9, 2013 at 11:40
  • What type of images are these? Maybe you're missing some plugins? Commented Sep 9, 2013 at 11:52
  • they are .png and .jpg images Commented Sep 9, 2013 at 12:19

    .png images should work, but for .jpg images you will need to add a plugin to your app. You have to copy qjpeg.dll from the imageformats directory located in something like C:\Qt\5.1.0\mingw48_32\plugins\imageformats. You put this .dll file in a subdir called imageformats that is located in the directory that contains your deployed .exe file. Commented Sep 9, 2013 at 12:32

This worked for me. Thank you.

Your problem is missing image plugins. You need to read about how to deploy a Qt application on windows.
