Php / MySQL - Using the UPDATE command to update a Primary Key?

Pretty self explanatory...

Here is my line of code, but it does not work because the field is a primary key.

The id is used to sort the pictures, and I want to be able to move the pictures around.

mysql_query("UPDATE pictures SET id = '$pict02' WHERE id='$pict01'");
