P.S. This line should let people pin the photos they use to their own ipfs node so that they can ensure robust file availability, with this page as an example,
for i in $(curl -s https://busy.org/@schrosct/overwriting-a-vps-default-install-using-swap | grep "img src" | grep -i ipfs| sed -e 's/.*ipfs///g' -e 's/".*//g') ; do ipfs pin add -r "$i" ; done
