General - Photo Gallery
Excuse the complete beginners question.
I am building a photo gallery using PHP and MySQL. When I show one of the photographs I wish to put a "next" and "previous" link on the page. Do I need to put these in a form so that I can send the id of the photograph to the next page to query the database for the next or previous photo.

next - previous images
Hi camdes, welcome to the forums.
You could use links with GET variables. eg Code:
<a href="img_db.php?img=3">Previous</a> <a href="img_db.php?img=5">Next</a> Where img_db.php tests for $_GET['img'] and uses the appropriate image.

Photo Gallery
Correct me if I am wrong, but as far as I can see, that would only allow me to see the next or previous one. I have not explained myself properly, I need to be able to scroll either way.
Another problem which has just occurred to me is that if I use the id field in my database, I will get an error if a picture has been deleted.
