Getting close to finishing. JVgalleryslider takes your existing Class Creator galleries and both gives you a sliding view of your images and if you click an image, blows it up to full screen (way more than default CC) and advances images (automatic not done yet).

Size of slider height defaults to 300 but can be set smaller or larger.

Images that are too small can be set to not magnify. Documentation to follow.

This is LINK TO DEMO. Other variations on the side menu bypass the Class Creator Gallery system and use any images in your file vault or anywhere.

I accidentally test an animated GIF and it looks like if it's below the reprocessing done by CC, it actually still animates.
