if you go to someone's gallery, it is identified by a user ID.
What significance does this play? How it it assigned?
Is it by when you join or post to the gallery,  or is it just a mystical number that is assigned?

Same for the images...is it in numerical order corresponding to the number o fimages in the gallery?

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
