[https://github.com/dennisvillasenor/popcorn-js/tree/0.7/players/slideshow github Link] - Connect to this github repoand fork a copy to your github account.   Coding and editing the .js file can be done with [http://www.example.com notepad++], [http://www.example.com Sublime], [http://www.example.com Textpad]or most any text editor. However, to test whether your code works, the entire popcorn directory you cloned as well as the slideshow.js file you worked on will need to be uploaded and run from a web server as the flash events will not execute due to Flash's security model.
