Using the jQuery plugin: http://www.appelsiini.net/projects/lazyload
causes some quirks. If you don't specify a container for the plugin, only the visible images on the screen are loaded, scolling down on a splitter pane shows that any other that were not originally visible are not loaded.
Specify the ID of the pane with the scrollbars + images causes them to all load at once. Changing the pixel threshold does not fix this either.
Has anyone else managed to get images to lazy load with any jQuery plugin with a scrollable splitter pane?
