Yes, absolutely right. Thank you. Here is the relevant part of that FAQ:
You probably didn't deploy image plugins with your application. You need to copy the contents of plugins/imageformats directory of your Qt installation to the imageformats subdirectory of the directory where you deployed the application binary.
For instance if you deployed the application to C:\Program Files\MyApp, you need to copy the plugins to C:\Program Files\MyApp\imageformats.
Imageformat plugins are libraries called "qjpeg", "qsvg", "qtiff", etc.
