I am not sure you need a separate interface name for each MIME type. Most 
likely the thumbnail service will have to decide about the MIME type itself 
anyway.

What do others think about having a signal like this

<signal name="Created">
  <arg type="as" name="thumbnails" />
</signal>

I know that "Create" is annotated as async but the client might want to start 
using/displaying thumbnails as the come in, e.g. in batches, and not wait 
until all requested ones have been completed.

Cheers,
