    Fixed memory corruption when loaded pictures are too big.
    
    This was causing the app to segfault under certain scenarios, and this
    "fix" solves the issue, although it would be worth it to invest some
    time investigating properly this issue since it could be that more
    memory corruptions or leaks were happening in the picture loader.
    
    Still, this is a good enough fix for the time being :-)
