Access Account Info For External App

Hi Tim - thanks for the recent look under the hood re database table. This leads me to ask two and potentially more questions.

I would love to ba ble to pass login information to a 3rd party support ticket system I run so users dont have to have a seperate account. 

I thought it might have been wp_users but theres not enough entries there to match the number of accounts shown of the dashboard?

Is there a good place you can recommened to learn some of this stuff so I dont keep bugging you and other users?

Is it possible to download photos unzipped or access photos from the database or back end? I ask with possibly or uploading in high res and working out a way to generate a print queue

So ms_people? Tim I saw another post stating that you don't want people writing back into sytist as that invalidates the software agreement. Is reading data out of it ok?

Any update?
