There is also sql injections when magic quotes are off. Maybe you tested with them on .

Example:
view.php?gallery_id=83'

Result:

View Images in:

A database error has occured.

mySQL said: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''83'' AND publish=1 order by id asc , id asc LIMIT 0, 12' at line 1

SQL query: select id, title, thumbname, added from snipe_gallery_data where cat_id='83'' AND publish=1 order by id asc , id asc LIMIT 0, 12

Example 2:

image.php?page=1&gallery_id=845&image_id=20'90

Result:

TestGallery - Error Getting Image
A database error has occured.

mySQL said: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '90' AND publish=1' at line 1

SQL query: select filename, thumbname, img_date, title, details, author, location, cat_id, keywords, publish, added from snipe_gallery_data where id='20'90' AND publish=1

Thats just two things you missed but there are many more.
