Randomizing Images

Hello. I love the plugin. It’s beautiful. I wonder if you can help me with a setting that I’m trying to configure properly.

I have a Flickr set that is about 100 photos in size. I want to load only 8 random images of the full image set on my site.

I can get just 8 images to load from the site so I know my setting to allow just 8 works. But it seems the randomize shortcode simply randomizes those first 8 images rather than pulling 8 random images of the total 100. I’d like visitors to see new photos each time the page loads.

Do you have any suggestions? Thank you for your help.
