Since the program implement more new features like systray and VIO commands (see CHANGELOG file), run photo setting 
a starting directory as parameter in the OS/2 program object notebook (or in a Command prompt Window).
I hope to be able to follow the project, since i don't use OS/2 anymore and i don't know how many progress 
the GCC  has made. Even though the program has been tested enough, it may randomly crash when trying to open some
particular jpg image, this is probably due to a bug in the qt4 plugin since on other platforms does not occurr.
Be patient, investigating.
Many thanks to Elbert Pol, surely my build environment is now a little more updated.
