Yo yo!
Are you ready for a bomb ?
OK sit back and keep strong :)))
FlepStudio has created a CMS for Flash CS3 galleries completely free !
This CMS is fully developed with Flex Builder 3 and the support of PHP and mySQL.
It's called Flex Gallery Pro

And is nothing more than an administration panel of a tunnel images developed in Flash CS3.
Very easy to install, already provides the Flash gallery but you can also create your custom gallery,
Calling a PHP (included with Flex Gallery Pro) who returns an output in XML format with the url of pictures, names and descriptions.
Everything run by a panel very easy to use.
