Easily reproduced with John's test;

echo 'digraph{hello->world}' | dot -Tjpg >hello.jpg
echo 'digraph{dpi="72"; a [label=<<TABLE><TR><TD WIDTH="50" HEIGHT="50" FIXEDSIZE="TRUE"><IMG SCALE="TRUE" SRC="hello.jpg"/></TD></TR></TABLE>>]}' | dot -Tpng > t.png

That works.

Change the dpi to a bigger number, and life is ... bad.

echo 'digraph{dpi="500"; a [label=<<TABLE><TR><TD WIDTH="50" HEIGHT="50" FIXEDSIZE="TRUE"><IMG SCALE="TRUE" SRC="hello.jpg"/></TD></TR></TABLE>>]}' | dot -Tpng > t.png
