Not sure if this is the wrong forum for this, If not I apologize.

Basically what I want is When a person comes to my url, they put in an "ID" Say like pic20413, Then hit submit, and ot brings that picture up.

I dont want them to see the gallery, just the images that I give them the ID to. Is there a script out there for that or would it be better to build it from scratch?

Any help would be appreciated.
