hi ya guys just wondered wheres are the files/downloads to upgrade to 1.4.2.3 and the download links to the new beta release arnt working?

Well, 1.4.2.3 can be downloaded from the download/home page of course. (http://www.zenphoto.org/)

The 1.4.3 Beta is in fact the latest trunk nightly build and can be downloaded here: http://www.zenphoto.org/pages/nightly-builds

Sorry, my fault! The download page now shows correctly the 1.4.2.4 release and not the 1.4.3 beta (fretzl is right).
