I'm not sure if this is something you did, but I'm uploading photos, and if I do the 'place inline' for one batch, and then upload more, the first batch stop saying (attachment=0)DSC04542.JPG(/attachment) or whatever, and all start saying (attachment=11)$matches(2)(/attachment)
(all square brackets turned curvy)
The pictures still show up fine, so maybe it's not really a problem, but it'll be a bit confusing if something has got muddled and you're trying to work out which picture is where!
