@vincepri as mentioned on slack, let's get this in as is (using LOAD_IMAGE) as this is the pattern we already have in CAPG, if we don't like it we can change all to the same pattern as a follow up.

Also, filed a backport to release-0.4 #1253 as the master is b0rked! and i need this somewhere that works
