  1. Introduction to Gallery Bharat Mediratta July 25, 2002

  2. What is Gallery • Open Source PHP application • Your photos on your website • Provides similar functionality to commercial ASP products like Yahoo! Photos, Club Photo, PBASE

  3. Brief History of Gallery • Started May 2000, small development team • Targeted at individual webmasters (me!) • Installed on 20-30K+ websites today • 200-300 new installs every day

  4. Why Do You Need Gallery? • You have a digital camera – and you use it! • You want the photos nicely integrated on your website • You don’t want to subject your visitors to advertising • You don’t trust dot coms with your data.

  5. The Gallery 1.x Challenge • Create an application with low barrier to entry to reach the broadest user base: • No database requirement • Don’t require custom PHP configuration (eg, compiled in GD, JPEG, PNG support) • Don’t require shell access to install • Run on Unix and Windows • Provide configuration wizard

  6. The Tradeoffs • No database  concurrency issues • External graphics library  config issues

  7. Gallery Configuration Security Problem Config wizard needs to create an output file, but we only want that file to be writeable at configuration time: Solution (borrowed from Horde) Create scripts to switch Gallery between configuration and secure modes

  8. Gallery Config Wizard Part 1 • Check out the user’s system

  9. Gallery Config Wizard Part 2 • Ask the user lots of questions and provide example answers

  10. Gallery Config Wizard Part 3 • Check the user’s answers! • The sooner we find configuration problems, the less time the user wastes

  17. Customizing: Change the code • The Open Source advantage: Add all new functionality to Gallery by modifying the source code
