I’m using the SwipeBox effect. It works perfectly in Chrome and Firefox, and on my phone.
In IE9, the first picture loads when you click on it, but then when you scroll the images don’t display. Just a flat black lightbox. If you hover you can see the alt-text, so it’s as if the image is there but just not showing.
Any suggestions? If this plugin doesn’t work I’m going to have to find another one, which is a huge shame as I love it.
If it helps with diagnoses, prettyPhoto works fine in IE. However, I prefer SwipeBox due to its better mobile compatibility.
