I agree, this could be a good way to handle the problem of malicious code,
but what I wanted to propose was also a "human quality control". In fact, I
see today that there is a lot of crap in the clipart (like broken or 0Kb
files), and lots of files missing keywords, so they are defacto unfindable
(pardon my english) and because of that unused (wich is almost the same as
So cleaning, controling and adding keywords to every file would be a great
improvement to the (poor) quality of today cliparts and at the same time an
possibility to filter potential hacks.
I really think we should do it because the clipart is growing fast and if we
keep it this way, one day we will end up with 1Gb of poor quality clipart
that no one would handle to open file by file to correct.
Also, there are lots of clipart files that should be deleted because of
their very poor quality or because they contain copyrighted graphics. Here
are some examples:

really a piece of clipart...)
By deleting crap, we could raise the overall quality of OpenClipart, so more
people and organisations would find it interesting to use or distribute.
