I think i picked up some garbage in your post??  Extra characters
following the '-print' or maybe some options I'm not aware of?

Anyway, I suspect your problem is that convert expects a source and
target and xargs is probably passing just a single file name.  I don't
really have time to play with this, but you can try the following
instead:

for fn in $(find /tmp/test -name product.jpg -print); do
convert -geometry 25% $fn $fn
done

Not as pretty, but should suffice, I think.
