Building plan

Here's the plan for the application ... well, really the final one. Previous drafts were omitted in sake of simplicity

As you can see, this is ambitious and sounds complex ... and it was. The complexity isn't around the code itself, but in the relationship between classes. Also not always the requirements of the pattern match your needs, and sometimes even it complicates things. But if you begin to allow exceptions, then things doesn't work as expected, specially when trying to modify your initial sketch.

Files

There are only three flash files: gallery.fla, videogallery.fla and bigGallery.fla. The first implements all variations listed, the second is specifically for the video example, while the third implements a couple of variations in a big format. All what you need to do is to coment/uncoment proper include based on your needs. All the folder structure cover the need of separate each combination of classes. The main folder have the basic triads, the mvc have the basic implementations for Model and View, the util folder have the basis for the Observer and Iterator. When uploading to the server, you only need the swf, photos or video folder and PHP stuff if you use the database model. That's because classes are compiled into the swf, not loaded at runtime.
