Allow me interject two observations:

1) You should tell the guy using Photoshop what Peter pointed out
regarding the Jpeg Quality setting.

2) Although it wouldn't be as flexible as your Python script, it's
completely possible and fairly easy to automate such a conversion
within Photoshop using 'Actions', which are like recorded macros,
coupled with the Automate | Batch... submenu.
