For the record, taking a leaf from Google's book in this area has
always been my preferred way of going about things. Also, to my
knowledge, Google does not use the highest level of censorship as a
default, but rather a moderate level (which is what I think we should
be doing also).
Google's "moderate" filtering acts on images. Google's
"strict" filtering
acts on images text. Google (at least the site I am shown in the
UK--other countries may vary) does not seem to have different levels of
image filtering.
