Do you update your paysite manually?

[R0ss]

The main goals of a CMS like MAS is not to resize pictures or extract blind thumbs from videos (although it can do it). There is nothing best than human touch if you have the time to do it.
However the main power of the software comes after you have pre-processed the photos and the videos. You don't have to deal with filenames, or create simple-looking galleries with some local software, then copy&paste html to create a better-looking gallery.
You can use the same content to appear in unlimited number of sites and members areas - all "dressed" in totally different layout.
You can describe your content with sophisticated categories and attributes, making it easier for you as a webmaster, and for the members to search and find what they want.
You can organize different photo and video sets in groups, creating "model portfolio" pages.
You can track usage stats, give your members the tools to rate and view the top rated ones, show them whats new and sneak preview whats next... and that's not all.

All this is a REAL timesaver, and some things you can't do by hand.

Not to mention, that after you have a site ready and setup with content, all you need to do to open a new site is just order the design templates. It will take you not more than a day to publish the new site live - and prefilled with content.

And finally - why risk to order a custom-made script from developers you don't know and spend hours and hours babysitting the new project until you make sure everything is done and working as you wish? The better choice is to get a product with a solid reputation, which have been tested and bugfixed by a number of customers with similar needs like yours. And rely on 24/7 support crew who will look after each issue you might have.

And I don't say this because I'm related with the company. That's just the smarter way of thinking these days.
