Beginner question

Hi,

I have a beginner question.

I'd like to create a uri like /photos/username/photo_id

So I have create a controller called Photos. But how do I have to call the function? The username is different every time ...

So far I have found how to get a segment from the uri to pass to the database ($this->uri->segment(1)

I hope somebody has some time to help me
