Klaus - You already have a reply to that point on Wiki.
Unfortunately, Moeller's comment does not help even if he was in fact intending (which I doubt) to override longstanding Commons policy that images must be PD in both the US and the source country.
Firstly, if you read the thread you will see that the comment was made in response to the closure of [http://commons.wikimedia.org/wiki/Commons:Deletion_requests/Images_from_Darw... a DR relating to Darwin Online images] as "delete". That DR has since been re-opened and closed as "keep", and Commons policy has been changed accordingly.
Secondly, the previous posting to which he was replying quoted Lord Oliver in ''Interlego'' as saying "But copying, per se, however much skill and labour may be devoted to the process cannot make an original work". As explained at [[Commons talk:When to use the PD-Art tag#Reply to call for revision]], that quote has since been explicitly disapproved by the Court of Appeal in the later Sawkin case. It is not wrong, but it applies in narrow circumstances only such as where an engineering line-drawing has been copied. The Court of Appeal has held that it does not apply in cases such as the present where the photographer has to apply significant skill and labour in setting up lighting, filters and so on.
Nobody wants to delete these images but Commons policy is that the image must be PD in both the and the UK. According to this recent case law, these are clearly copyright images in the UK.
