Not a clue

Thanks for providing the plugin, but not a clue how to use it.

You demo is using a flickr stream it seems which gives no insight into how to get the image data into the your function.

I'm moving on because there are other options. I'd recommend making a demo which is replicable or the HTML + JS + CSS needed to make a working demo.

Same issue here

I also dislike that you have to link the pictures in the JS. Would be a better solution IMHO if the source of the pictures would be in the DOM in case of someone has disabled JS and SEO.

Same here, no clue on how to implement it...

There is also the option of inserting the pictures list in the page itself in a js variable so you don't need to fetch the images from an external source.
For example I use something like:

<script>
var photos = [{width: 4000, height: 3000, url: '/path/to/myfirst.jpg'}, {width: 2000, height: 2000, url: '/path/to/mysecond.jpg']
</script>

The content of the array can be pretty much anything you want as you can write your own getSize, thumbnailPath, template, etc. methods.
