Not sure if this is the correct sort of question for this forum so please feel free to point me elsewhere if appropriate.
I am looking for an Open Source Picture Gallery (probably PHP) to use on our website for allowing members to upload their own pictures. The problem I seem to have encountered is that many of these operate as standalone pages and are difficult if not impossible to truly integrate within an existing website. I know many have the ability to create custom Themes but that really isn't the same thing.
So question is can anybody suggest a good open source picture gallery which can be Fully Integrated into our existing website layout, keeping our Header, Menu, Quick links panel, Footer (floating) etc.
