I have a table for image gallery with four columns like:

foid | uid | pic1  | pic2  | pic3  | date     |
-----------------------------------------------
104  |  5  | 1.jpg | 2.jpg | 3.jpg | 2010-01-01
105  | 14  | 8.jpg |       |       | 2009-04-08
106  | 48  | x.jpg | y.jpg |       | 2010-08-09

Mysql query for the user's galleries looks like:

SELECT * FROM foto WHERE uid = $id order by foid DESC

The thing that I want to do is count the number of images (PIC1, PIC2, PIC3) in every of the listed galleries.

What is the best way for doing that?
