Take an existing directory hierarchy of pictures and use it to organise the album/gallery. Don't copy the pictures, use them direct from the existing directory structure. Must not require any write access to the pictures directory. The thumbnails and other information must be stored elsewhere. No need for any picture manipulation at all, just a way to navigate through the hierarchy and view the pictures. Preferably no database and the ability to use EXIF information but these are not absolute requirements.
I suspect bpgallery.sh either does this or could be persuaded to do it without too much effort. Depends if by "web application", you mean something doing it live, rather than precompiled. http://sommitrealweird.co.uk/development/bpgallerysh/
Hope that helps,
