Hi pixel8,
I looked at your URL but all I see is the default WordPress image gallery and not the gallery inserted via the Easy Image Gallery.
Also, you have a JavaScript error on that URL you provided (looks like it’s related to some sort of twitter widget), which will break all JS related to that page. Easy Image Gallery uses JavaScript to open up each image which is likely why it’s not working in your case.
Try making a new page, with no widgets, insert a gallery and see if it works. Send me the URL and I’ll have another look. If you can, email me at [email protected] with a temp admin account and I’ll take a closer look for you.
