Hello,
If you want to display only the first image from Flickr photosets and if a user clicks by this show others, you can choose 'Single image' layout type in module settings. Copies of 'ARI Fancybox' module can be created if need to show different photosets in different location with different settings or if you need the same settings and only photoset ID will be different, 'System - ARI Fancybox Anywhere' plugin can be used. You can set default settings on plugin settings page and set necessary photoset ID in {arifancybox} plugin tag. Regarding problem with JCE editor, could you provide temporary access to your Joomla! backend by
email and say link to page where we can see the issue that we can investigate it and provide solution?
Regards,
ARI Soft
