I'm having a hard time figuring this out. I have a photo album that displays
one image at a time. I want to have Previous and Next links for images in
a users album. This was suggested:
but it seems to be more for a number of results instead of one.

At first I used the id field which is auto_increment and did -1 for
previous +1 for next but then realized if they delete an image in
the album the id field is no longer successive by 1. I can count
the number of images in an album but not sure how to know which
is the first, which is the second etc. and know which the current
one is if the id field has gaps in it. Not sure if that made any sense.
