i use a photo gallery script i found on DYNAMICDRIVE,
it works great, and uses PHP to automatically add pictures to the page (all you have to do is config some javascript, then upload pics and the included php file... it works great, and no editing of the page is needed...
there's alot more info on DD's site:
"
dynamic drive photo album script
i love this script because i can't install much on my server (godaddy basic) since i can't get to the admin console.
this script works great, check out our
galleries
the cad, 2007 build season, and 2008 build season all use this script
hope this helps!
