Clearly showing my ignorance (or youth :-) I didn't know eps was a
vector format. Thanks for the enlightenment Paul

That Bob Stayton again :-) Neat.
  Again I didn't know ... OK enough of the self-flagellation

Generalising the question then (for my education if no one else's),
Are there 'quality ladders' that are common?
and I guess I'd better caveat that as for either being html and PDF.

What are peoples preferences? Which ones do you avoid, always choose?
What are the considerations.
Clearly I'm less fussy, I always go for png for both. Jpeg if png
not available.
