Public bug reported:

I frequently hit the use case that I query some host (might be in my
local network, might be on the internet) for a list of things. The
result set comes with images so I present a scrollable list of all those
things to the user.

Problem now is that with the images being fetched, the list scrolling is
somewhat stuttery and also presents empty images at first which then are
only filled with content a bit later. Scrolling the list back up, same
thing again happens as the in-QML caches we have are based on RAM and
with that can't hold tons of images. They are discarded and scrolling
the list back up causes them to be reloaded.


It would be great if the Thumbnailer could take care of this and fetch and cache them for the developer.

One point to think about would be timeouts. Some use cases will always
present the same image again. For example in kodimote I fetch the music
artwork given by kodi. The artwork won't ever change, so the cache can
be persistent. At the same time, fetching things from an online server
*might* change over time. Ideally this would be configurable so that the
developer can specify some cache time out for entries.
