问题
I made a user interface using Qt Designer qith Qt 5.0.1, and I used icons from a resource file. After compiling, the executable runs perfectly fine, and the icons are displayed as expected. However, when I run the programme on a different computer, they mysteriously disappear, and I am not able to get them back.
What can be the reason for this? I thought that the resources where hard-coded in the executable after compilation, but that may be wrong. In any case, I find it very peculiar that wherever I move the executable, it displays the icons on my own computer, but not on another one's.

I think you're missing some plugins. If you're using Windows and your icons are .ico type files, you need to copy the qico.dll file from the imageformats folder located somewhere in your Qt folder (something like C:\Qt\Qt5.0.1\5.0.1\mingw47_32\plugins\imageformats) to a subdir called imageformats that you create inside the directory that contains your deployed .exe file.
