Im using image galleries in a site with K2 as the content manager for the most critical part of the site. The galleries in the K2 Items are displaying one thumbnail only for all the images. On click teh images all display correctly, the cache is being created and all the thumbs are in the cache folder. The plug-in is displaying only one image on each page. I have the pages linked up to several menu items as K2 category type menu item and K2 item menu types, each page displays a different thumb. each PAge is displaying the last image in the array. you can look by going to gsp-corp.com and log in as user name is Arenauser, password is 12345 temporarily.

Hello Williard,

It is related to a caching/ performance plugin you are using.
Since this is related to Simple Image Gallery Pro, please open a ticket on our helpdesk.

I have no budget for a subscription right now I can open a help ticket. But sadly I can install something else if I need to.

This issue is from a 3rd party caching/ performance plugin.
It transforms images to data uri. Disabling or tweaking that plugin's setting will solve this issue.
