for osCommerce Online Merchant v2.2

Here is another contribution to Oscommerce. I was a litle tired of watching to the old design of the administration in oscommerce shops, so I decided to improve that. I think that its ok and more atractive. I also include in this files, the login / logout for the admin ( se the instructions to install..). Also included new buttons (Plastic type). New colors and icons. See the layout.gif.
