The software I am trying to use ( a flash gallery) has the following requirements:

This application requires that PHP version 4 or higher, the GD library, DOMXML library and the iconv library extensions are installed on your web server (iconv comes on most Un*x-type OSes).
Do I meet those requirements? Because the application is not working, it wont allow me to login. I press the login button and it does nothing.

Thank you,
Mishka
