Caching images, thumbnails and sprite

[jeyjoo]

Hi
Im on version 1.7.6
My gallery is http://www.jeyjoo.com/gallery/
I was wandering if there is a way to cache images, thumbnails, sprites (everything that will not subject to updates) to improve page speed.
Thanks,

Mike

  Ok thats great.
I use Firebug to test page speed - it was complaining that images weren't cached!
