I don't script Photoshop, but I noticed this line in someone else's 
script yesterday:

open thisFile showing dialogs never

Of course, that doesn't suggest anything about telling how the 'open' 
event was initiated, and I don't know if PS distinguishes error cases 
when opening documents. That's just an example of a possible interface 
for scripters to suppress user interaction.
