You'll need to rename imagename.exe to something else, I'd suggest _magename.exe (_pqkygrp.exe as an example) and copy this program to the folder you found that imagename in and rename it to the original application's name.
Click on that HP Photo & Imaging Director button again, this will open a dialog with the complete command line, copy this command line and create a shortcut in either your Quick Launch toolbar, or on the desktop.
Repeat this process for each of the buttons in this launcer application. It may work for other applications too, but this was my own challenge and I figured I'd share it with you.
Remember to rename the program back to what it was called originally, and keep WinEcho.exe for the next time you need it.
