Hey UncleCheese,
New Silverstripe user, so far loving it, just so simple, although I definately think I need to learn more PHP.
So I have had a bit of trouble with your Image Gallery plugin, first it wouldn't let me save pages, and took me a good 4-5 hours to work out it was because there were previous versions of the pages saved so had to delete those manually via PHPmyAdmin
Anyway I got through that issue, the issue I now have is, as a logged in user, you view the gallery page, and all the fancy box stuff will work, but when you log out and goto the gallery page, it just does not want to work, all JS files are there, so I am not too sure what is wrong. I am using your current files from github.
Tested in Chrome, and Firefox 6.01
No JS errors in either firebug or chrome.
I am completely stumped, I have already spent a good few hours trying to figure it out.
You can view the gallery page here: http://www.ambria.co.nz/view/
Can you please give me a pointer in the right direction why this is not working.
