There is a class on UT that lets you launch an EXE and then wait until it exits before you carry on.

When they check it out store the user, date/time checked out and the temp path copied to (e.g. c:\tempimage). You could optionally launch the image program at this point. You could also have another button "check back in" which would copy back the new version and clear out the user and date/time checked out. I would definitely go for storing the path rather than the file itself. As for checking things back in on app shutdown, you don't know at this point if the changes are complete, so would leave this up to the user. Other things to consider are can anyone else book out the image (and if so whose changes take preference?). You may also need another button to clear the check out (don't save changes) Just a few ideas.
