I’m still working on it.
Turns out the API for the DVD covers website I was planning on using doesn’t work, which was a bit of a setback. I have a workaround though (embedded web browser – find the cover you want, touch it, and then press a button at the bottom of the screen) which is a bit more complicated, and a bit slower, but it does work. A pity I spent so much time writing code in preparation for using the API, and now I can’t use any of it 🙁
