I'm using the latest version of WordPress and the latest version of NextGen-Gallery. I have several galleries to which I add pictures regularly. All galleries and pictures are displayed properly.
I also link the images in my posts using the singlepic feature. It always worked well. In the latest post, I have a weird problem, though. All singlepics show up but two. I have deleted the images already and re-uploaded them so that they have a different id. I changed the size, well I tried basically everything. They appear in the gallery on the photo page but not in the posting via the singlepic-id. Any help? :P
