Tips for a faster website
===

I would like to know if there are any tips and tricks for my site to load faster?
<br/><br/>
For example in my site I have 4 groups of background images that switch when hover..<br/>
is there a way to load them before? <br/>is there a jquery plugin for that?

If I echo in php a div with all the images that are in my site with display none before the DOCTYPE. will it help?<br/><br/>
and general tips in for html/css/jquery?<br/><br/>
All suggestions are welcome...

Thank you.
