Are you using a jQuery plugin? If so check if there is an option in the documentation If not you can search for a plugin that does that. Or you can try the lazy load method

Felix Yakubov I think they're just learning jQuery now and plugins may be wooosh over their heads atm (but you never know!). However, I'd really appreciate an explanation of the lazy load thing you're talking about :)

Lazy Load (wiki entry): Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed.

Example: lets say you have a page which has a gallery near the footer. Why waste time and wait until the images load if you don't need them right now (or maybe at all if user won't slide down). Lazy loading lets you load those images only if user needs to see them. https://css-tricks.com/examples/LazyLoading/

Some plugins using lazy load:

Its one of the main JS optimization tricks you can use to speed up your website (making it more user friendly and seo friendly) Async loading uses the same idea but with js files
