Semantics can be an obstacle. I opened Synaptic after reading your post and
searched for "clip art". I got a lot of results, none of which appeared to
be clip art but when I tried again, searching instead for "clipart", I got
specific and usable results. When I'm looking for an application for a
specific purpose I don't normally begin with Synaptic. I begin with
google. Of course if you google "free clipart for LibreOffice" you'll need
to pack a lunch because it'll take a while to screen the results. It's a
bit of a mixed blessing. :) Of course if I were a total novice wanting to
make a fancy poster and searched "Poster software for Linux", I'd get
fairly useful results. In either case, the answer you get is only as good
as the question you ask. My point is simply that if you can't get an answer
to your question, consider rephrasing the question. :)
