That seems like a good idea.
Note that if the first image is not compressed, we may have a similar problem
with WAN accelerators. Also maybe it is better to always compress it.
This random buffer was intended as a quick fix.
In the long run, we would like to measure network statistics dynamically, e.g.
when sending large images (as you suggested for the first one).
