micdee on "Ipad and Zen Photo"

I have searched on Google and this forum with no success. I am trying to upload photos or Files to Zen Photo but when I log into Admin the option to upload photos or files are greyed out when I use an I pad. When I go to a PC there is no problem. Please let me know what I am missing. A Plug in? or .....Anybody have time to let me know what I need to do to make it happen?
Thanks in advance
