I realize this is custom work but thought I'd ask in case anyone has tried. As you know, PrettyPhoto's lightbox looks terrible on mobile devices. Raygun has a plugin that works with wordpress gallery - when you click on a wordpress gallery thumbnail, the gallery opens in a mobile ready lighbox.
Has anyone tried to disable the pop-up lightbox on PrettyPhoto to open Raygun's mobile friendly slider? ie: http://www.v-u.ca/files/slider.png
This plugin attaches a PhotoSwipe-powered mobile slideshow to the built-in WordPress [gallery] shortcode. To use the plugin, simply upload images to your post or page and click the "Insert Gallery" button. Make sure your gallery images link to the image files and not the attachment pages. The shorcode will look like [gallery link=file]. That's all there is to it! The plugin will take care of the rest.
Thanks! I'm desperate to find a good solution. Fancy box was recommended but it doesn't look good either.
