Ajax Update Panel and Lazy Load image

Hi All

Can any one suggest me how I can develop lazy load images so when user scroll page then image loaded. I need to use these images in Repeater and Repeater will be placed inside Update Panel.

Already I tried jQuery lazy laoder which are working perfect but when any event happening in Update Panel then all images disappear and showing loading in progress image (usually set in 'src' for all types of lazy load jquery plugins).

Thanks for reading my question
