69046 Gallery system

I need a custom gallery solution. It needs to support pictures and videos. Videos need to be supported as http streams and direct downloads.. with the choice to enable and disable each option for each video. A video needs to have an own thumbnail preview, a field for a brief discription, the optional download and/or stream link, and three (or more) optional folders ( like captures, photos, misc). Each of these subfolders can have its own thumbnail as a folder-icon. Within these subgalleries, pictures are displayed as thumbs in a well sorted manner, with freely selectable thumbnail size, rows and columns. All layouts should be template driven for easy visual manipulations. For single picture galleries, the same options should be available. Within the galleries, people should be able to posts comments and rate pics and videos. Another template should enable me to display the 5 most viewed and the 5 highest ranked pics and the pics with the most recent comments. Another template should offer the same features for videos. Within picture galleries, people should be able to activate a checkbox below their favourite pictures. The selection needs to be stored in a database or so for every single user. Pics with activated checkbox can be displayed in their own slidshow. And they need to have some sort of personal gallery, where they can view their selected pics in a normal gallery. A normal slideshow funktion needs to exist for a single gallery, all galleries and there also needs to be a shuffel option for both funktions. User should also be able to have their own little gallery, where they can upload pics and movies. Also with the option to get rated, commented by others. These uploads need to be moderatable. I also need an admin section to easily adjust all settings and take care of the gallery. Mainly the gallery should be stand alone... but if possible, planed integration into PHP nuke, XOOPS would be a cool extra. System is linux with mySql. PHP or CGI does not matter as long as the rsult is what I need. Gallery will be running in a password protected area. (Apache/htaccess)Would be great if the system can recognize the user to automatically enable his personal settings and selections for him and to automatically use/display his username when posting comments. But this has to be optional, so that the system also can easily be integrated into existing CMS. System needs to be built in a modular way to easily add features later on, if needed. An installation script would be also a nice feature... See also attached first drawings and discriptions.... if you can read my bad english and bad handwriting :)
