Need information about privacy system (developer)

Hi,

I'm developing a slider in a new block in my homepage.

This slider will display the latest public medias and events (photo, sounds, video, events ...).

I thought simply do the necessary with simples database queries to display them, but with privacy settings, it's more complicated. I don't understand how the privacy system is designed (I don't see any table for privacy settings with photos module by exemple).

I saw 1 class which could be interesting (BxDolPrivacySearch) but after taking a look, i feel this class is used for profiles only ....

Is there somebody who can me explain how i can proceed ? I have knowledges of PHP/MySQL but i think that some informations for me are missing or I haven't the best method to find this informations

Thank you.

If that could help somebody, I post what I found this afternoon.

It seems the privacy settings are controlled with the album. All datas are in the table bx_photo_main, sys_album_object and sys_album. Now I can do my query.

But if you have a method more easy, I would like to know what is your method (like using a bx_class).

Thank you.
