I got asked whether I could create a table of packages with the thumbnails 
shown already (or perhaps a checkbox to enable that in the usual table). 
That would save some clicking and navigating.

Perhaps I can put a Squid in front if that really affects performance. 
Until the service is heavily used and linked from packages.d.o I don't 
expect much load though.

Currently it's per binary package. It has the advantage that users (who are 
the main beneficians from the screenshots service IMHO) don't care about 
source packages but want to see screenshots for the packages they can 
install in synaptic or aptitude. Some of the binary packages (e.g. *-data 
or *-dbg) don't really need screenshots. I'm working with Enrico's nifty 
debtags soon to fix that.
