The 1.9 version of the org.devlib.schmidt:image info library is used everywhere else (dam, data, legacy-adminiterface, …), but the magnolia_main/pom.xml still defines the 1.7 version. This leads to inconsistency (1.7 version in WEB-INF/lib, 1.9 in add-ons), and could also cause a compatibility problems if we hit an API change.
