I'm using imagesLoaded to help me with my layout using the dotdotdot, masonry and infinitescroll, and I have it working just fine in all browsers I was testing it in, however, when it came to making sure that the site could handle an orientation change, I added the following meta tags to have iPhone safari scale back down http://stackoverflow.com/questions/2581957/iphone-safari-does-not-auto-scale-back-down-on-portrait-landscape-portrait.
However, once I did this imageLoaded just stopped firing. I'm not looking for a solution, because I'm probably going to find another solution to detect an orientation change so that users can still zoom etc., just wanted to know if this behavior is known, expected, explainable?
I tested this with v3, and I was unable to reproduce this error. I am recommending you upgrade to v3 and see if this resolves it for you. Please follow up if you continue to have issues.
