Simple, easy, perfect.

Pretty easy plugin, much easier than pasting javascript into my posts. Thanks a lot, works like a charm, keep up the good work!

Simple, fast & slick [5/5]

I searched for quite a while to find a ‘zoom’ plugin that did what I wanted with little fuss, and tried various plugins before settling on this one.

I am impressed by how quickly this loads on my page, and how smooth the zooming and navigation are.

I had a small issue, and Alexey the plugin developer issued a fix within a few days – good work. 🙂

I just needed a little css for my theme, with this simple shortcode (if it helps anyone) –

[gallery ids="331,328" openseadragon="true" width="1076"]

Use WP editor to add a gallery as normal, then edit the shortcode to add in the openseadragon parameters.
