      Hi everyone,

      I wrote a little application where I load and treat some images using the class QImage. Everything works well as long as I load images in the png format, but when I try to load jpegs, the program crashes with the following error:

      Wrong JPEG library version: library is 80, caller expects 62

      Anyone knows what to do in such a situation?

      Thank you very much.

      Mike

        Did you try rebuilding Qt with the newer jpeg library?

        Of course you could also downgrade your jpeg library, but downgrading a system library is usually more tricky than just rebuilding Qt.
