I'm thinking of a parallel way of the music streamer: You have pictures in a directory on your server and the pictures are 'transcoded' (resized) into a viewable format (~100kb jpg's). You need to be able to convert big jpg's as well as all the RAW formats. For Linux the tool Ufraw could be linked to this feature.
I'm not sure how many people would be interested in this, I sure am.
/Offtopic: Thank you so much for creating this amazing piece of software Sindre! I've migrated from GNUMP3D to this, it's so much nicer to use and the app integration is just great!! Purchased a license after one day of install
