The whole point is that they *aren't*' putting blobs in their database -
that has way too much overhead. They're using a custom service that does
nothing but "read from byte X to byte Y". No concepts of tablespaces,
integrity, indices, whatever.
The only thing they store in their database, is the start- and end-byte of
each image.
I doubt they even took it as far as to write a plugin engine - that would
again bring too much overhead.
