Hey Jdudeo,
the gallery problem hasn’t been reported before and I cannot seem to re-create the bug on my installation – the large-size gallery posts work fine on the demo. Could you please provide access to your back-end so that I could troubleshoot the problem? I will need to ask you for the admin login/password as well as ftp URL/login/password (if possible) – you can send them to support@satoristudio.net; no disclosure guaranteed.
Sincerely,
Andrew / Satori Studio
