Audio + picture presentation: possible contribution

[cainesap]

Hi, I wasn't sure how to contact you except via a pull request. In the readme you invite contributions from the community. Firstly, thanks for the great resource! Secondly, a student I'm working with wanted images displayed with the audio files. So we set this up, requiring changes to design.js, a new .ejs view type, a new column 'picture' in index.txt, and a new directory 'resources/pictures'. I can contribute this, if welcome?
