The zoom is based on some code found on the web. I created it first in RBB, but now also in SD3, so that it can be saved as a component. If you want to add more images, then just give them the same class as the ones already built in.
(The original component was created before RSD had all the smart transition and scaling options)
The 3 first images are from Dublin, and the last 2 from Carrickfergus and Larne in N-Ireland.
Open the file and select the container 'wrapper' to create a component. If you want to use it on a site, please provide your own images.
