Today I found myself in a complex codebase and my ticket was: this JS on this old page makes the monkey dance, can you make it dance on the new page? Well, my JS knowledge is... limited but I have a really mean right click. So I right clicked and looked around the source Chrome showed me. There was a div with a class slideshow-node-embed-processed. Now that's important: -processed is added by the jQuery once plugin that Drupal 7 happens to ships with. It's much easier to recognize the handiwork of the plugin than actually use it -- this is true for many similar reverse engineering scenarios. Next step is ag slideshow-node-embed (you have ag installed, don't you?) which comes back with a single JS file called sites/all/themes/foo/js/node-embed.js. Next ag -A2 -B2 node-embed.js -- just searching is pointless but by adding some context to it hopefully we can see some settings or CSS necessary.
