As a web-app developer I want to let my users select existing images from their POD or upload new ones for special purposes - for instance when writing a blog post and then adding an image to it, in which case the user can either upload a new one or select an existing one.
Where should new images be uploaded to - and where should the user be looking for existing images?
It is very similar to mobile phones - if I want to add a photo to Facebook I can either select an existing one from my phone or upload a new.
I assume there exist some sort of standard for this purpose on Android/iOS - and I guess it would be beneficial for Solid to have a similar approach.
Further more, it would be nice, as an app developer, to be able to reuse some sort of standard Solid widget for selecting or uploading images (or documents in general).
