Android :: Display Multiple Images From Remote Source In Gallery - Zoomable - Pannable

I want do display some images that I load from a remote source in a gallery. The gallery should let the user do the following things:

-zoom the image (preferably also by pinch-zoom) -pan the image -switch between the different images

Of course most built-in gallery applications can do all of that. So my first idea was to use an ACTION_VIEW intent in order to delegate the task to some gallery application. This however won't work for me since you can only pass the URI of the image you want to display but not the actual bitmap data itself. I can't just pass the URL of the remote image because I need to manage the loading and caching of the data myself. A way around this would be to write the data to a local file and then pass the URI of that file (and deleting the file again afterward). Besides this being less than elegant it won't even do the trick because with an intent like this you can only pass one image at a time.

The built-in Facebook application on the Nexus One actually does exactly what I have in mind for displaying photo albums. It looks like a custom gallery activity they built into their application. Does anyone know whether there are templates available for something like this somewhere that one could reuse? Building something like this from scratch by myself seems too time consuming.
