Hi Saxman, Here's a possible explaination:----

http://www.pbase.com/help/recently_upda ... ies&id=129Why is my gallery not in the Recently Updated Gallery list? In order for your gallery to show up on the updated gallery list, your gallery must contain recently added/ new images. If you reformatted or edited existing images in your gallery, your gallery will not show up on the list.
You must also be a paying customer.
If your gallery is already in the list from an upload in the past 2 hours, it will not be moved to the top of the list.
If you have been abusing the recent gallery pages by bumping your galleries without truly adding new content, we may completely block your account from the recent uploads page.
