jAlbum is equipped with BeanShell, a very powerful Java-like scripting language. Scripting gives you the ability to add any imaginable features to generated albums. Within special <% scriptlets %> you can construct just about any expression you like that is also valid Java. Scriptlets can be embedded into the template files of jAlbum skins (index.htt and slide.htt) or inside style sheet files of skins.
Here are some examples. Copy and paste them into a skin to have them executed during album creation.
