Nothing gets lost or is a mess. Apparently the forum software authors just tightened the grip a bit to strengthen security (at least that’s my guess), so more stuff than before may require manual approvement before it gets published.
Sorry, didn’t check your latest mail yet. That should be easy to circumvent then by just posting one image per post. There is no option to change the number of allowed image links in the backend unfortunately.
If something else happens: just shoot me a mail if another post of yours requires manual approval.
