Hi,

Can you test what happens if you convert the jpg files to png and use those
instead? There have been problems with loading JPEG images in Qt under some
circumstances.

wow, now it works!
but it would be great to get a true fix for this as i have heaps of jpgs and converting them needs lot of time and even more space.

Yes, I know. The fix might be to just re-build the windows version. I could not get mxe running anymore the last few times I tried as some required packages failed to compile, but I should receive a new SSD in one or two weeks, then I can try again (HD is full too atm).
