PyQt app: gif files don't show after compiling with py2exe

Question

For some reason on my system (Windows XP 32-bit, Python 2.6) PyQt is able to display gifs perfectly when run in the python interpreter, but when I run it through py2exe, they no longer display.

I've tried everything I've googled: copying the gif DLLs from PyQt into an imageformats/ folder, setting up a qt.conf (as another stackoverflow thread suggested), done a setLibraryPaths to where the imageformat DLLs were, copied the setup file from http://wiki.wxpython.org/py2exe-python26 .

Nothing seems to work -- what on earth could I be doing wrong?

Convert the gif(s) to png(s) and in your application use the pngs instead of gifs. I faced the same issue but couldn't explore the cause of the issue. Using pngs instead fixed the issue for me. HTH. — sateesh, Jan 31 '11 at 09:34

I'm not sure how you even managed to compile PyQt with py2exe; I had no success, and switched to pyinstaller.
Py2exe wasn't cooperating well PyQt and refused to compile depending on what widgets were featured.

I'd recommend switching to pyinstaller for compiling PyQt; see if it allows what you want in this case

Sometimes using compilers is a little daunting; ask for help if you need it – Anti Earth Dec 22 '12 at 05:10
I have had no trouble using py2exe in the past with pyqt until I switched to pyinstaller. Guess you just had poor luck :-/ – jdi Dec 22 '12 at 05:17
This is surely some kind of conspiracy :/ – Anti Earth Dec 22 '12 at 05:26

from distutils.core import setup
import py2exe

Just in case anyone is in this situation, I found the solution. These is what you need to do when compiling with py2exe so your image files are shown:

All the image files (gif, png, jpg) need to be copied to the dist folder
Qt dll files need to be copied from Qt installation folder to dist\imageformats

For the dll files you need to set this on your setup.py file:

windows = [{
            "script":"yourPythonScript.py",
            "icon_resources": [(1, "nameOfIcoFile.ico")],
            "dest_base":"nameOfExeFile"
            }],
            data_files = [
                ('imageformats',
                [r'C:\Python27\Lib\site-packages\PyQt4\plugins\imageformats\qico4.dll',
                r'C:\Python27\Lib\site-packages\PyQt4\plugins\imageformats\qgif4.dll'
                ])],
)
