Currently in the worst case images are transformed
from Extbase domain objects to FAL objects to paths
to FAL objects again just to render an image.

Avoid back and forth conversions an directly use
FAL API instead of using the detour through
the content object renderer.

Resolves: #53700
Releases: 6.2
