My knowledge on JavaScript & PHP isnt that good yet .. Sorry if this its a silly question but I don't know a quick way to do this:

I'm working in my own model agency website and I would like to know how to build the model catalog section (where the models will show up).

• First in the model catalog I wanna show up all the models with them names below the photo
  ( Here is an example: http://cnmodelos.com/modelosNacionales.php?provincia=1 )
• Second when someone click on any of the pictures can go to the model info and extra photos
  (Here is an example: http://cnmodelos.com/datosModelo.php?id=4 )

so far as i know that could be done on JavaScript and PHP

But here come the biggest questions:

1. Can be done with wordpress theme maybe with a plugin?
2. Can be done with oscommerce or magneto?
3. Is there any place where I can download a template for my model agency project (Im not looking for XML or Flash templates) that has a administrative console like oscommerce or wordpress.

I hope someone give me any idea on it......

To answer the 'biggest' questions:

1. Not sure, never used wordpress
2. Oscommerce is a shopping cart, and yes, you *could* use a shopping cart, but I don't think that would be the best for your situation...Have you looked into a modeling script? I'm sure if you google modeling scripts you would find something more suitable, unless of course you want to sell from the catalog too. But you didn't mention selling anything.
3.Google html templates (you will find some free ones)

This is supposed to be a cms for a model agency type site: Be warned, the site did contain an adult video playing: http://www.thaxroads.com/
