A new version of the PonyTab with almost all requested features is out, check the Download section:
www.joomlapolis.com/component/option,com_docman/task,doc_download/gid,45/Itemid,36/
Now configurable with a link to the Ponygallery Userpanel, and the image category displayed. Plus, it display the descprition of the tab and the number of pics per page can be set different from the PG-settings.
Just uninstall the old one, install the new, publish it and set it up as you like in CB-> Tab settings.
The problem with pagination with nested tabs enabled as described
here
is still irreproducible for me, when I enable nested tabs, everything works as usual.
Can someone have a look at the pagination code I use?
