Before the images were hosted on a separate domain. Since we don't
have that, we moved them in libreboot/img and the address were changed
with the following command:
$ sed 's#av\.libreboot\.srht\.site#libreboot.srht.site/img#g' \
-i \
$(git ls-files | xargs grep "av\.libreboot\.srht\.site" | sed 's/:.*//' | sort -u)
