Use:

  SELECT YEAR(t.ur_date_field) AS yr,
         MONTH(t.ur_date_field) AS month_number,
         COUNT(*) AS num_photos
    FROM UR_TABLE t
GROUP BY YEAR(t.ur_date_field), MONTH(t.ur_date_field)
ORDER BY yr, month_number

…to get:

yr    |  month_number  |  num_photos
--------------------------------
2010  |  1             |  2
2010  |  2             |  1

If there aren’t any photos for a given month, it won’t show up in the resulset.

From there, you can validate the month in particular.
