Flickr limits the amount of groups a photo can be submitted to. Pro members can submit a photo to up to 60 groups. Non-pro users can submit a photo to a maximum of 30 groups.

It looks like this is the case for you. There is a option to opt out of this and allow photos to be added to the group regardless of how many groups the photo is in.

Is this something as a group we could do?
