I am an artist and journalist. I have created a photography exhibition which has 21 photos, each paired with a short podcast with an interview about the photo. These are around 2 to 3 minutes each. After seeing a lot about audio description lately, I want to add a short description of each photo to the start of each podcast and have them on a platform for VI listeners. I currently have the exhibition built into a web app as well, but I definitely don't think this is suited to screen readers... I'm still learning about web design.

My question is, would this version of the exhibition be best in a platform like iTunes and other podcasts apps, where you could just download or stream the whole lot from there? These files would be different copies to those I've put in the web app, with the audio description included, and the podcast name and description labelled as such.
