Ok, thanks I see that there is a reference to http://jira.xwiki.org/browse/XWIKI-12871
Is it really an objective of the 7.4 or might it be moved to another later release ? Can I do about it beside waiting for 7.4 to be released ? Can I upgrade a component myself as a workaround ?

From what I understand the image format is too recent for the old FOP 1.1 version we are still using.
