Schedule image pop-up using task scheduler

Solution 1:

Found it. If you want to open the image file using windows photo viewer (Ive done this in win7 actually, should work on 8 too) when you are in task scheduler, hit Create a basic task and give a name and time and in the Action part hit Start a program and in the next step in the Program/script part put this:

%SystemRoot%\System32\rundll32.exe

and in the Add arguments (optional) paste the text below and remember to substitute __PATHTOFILE__ with full path of the image file like C:\Users\Jack\Desktop\file.jpg without any quotes:

"%ProgramFiles%\Windows Photo Viewer\PhotoViewer.dll", ImageView_Fullscreen __PATHTOFILE__

Like this:
"%ProgramFiles%\Windows Photo Viewer\PhotoViewer.dll", ImageView_Fullscreen C:\Users\Jack\Desktop\file.jpg

And Finish!
