Would it be possible to do this with .htaccess?

Hi all, i have some pages that i want to use .htaccess on, the file names are below:

photos_something.php

Would it be possible to make them appear as:
/photos/something.php

so they would appear in a doman as:
http://www.domain.co.uk/photos/something.php

instead of:
http://www.domain.co.uk/photos_something.php


I am just wondering whether i can do this using .thaccess because it would have to rename the file by taking out the 'photos_' part and then create a virtual 'photos' directory.

Thanks very much, Ryan.
