How do I force the cache to work?!
 

What do I need to do to make a person's cache or history to work?

It seems that my site is having to load all the images everytime. I want a little more speed and so I want to make their computer to show previously cached images or whatever.

How do I do that? By setting a cookie? Or with some meta tags or something? Does anyone know how to do that?

For example if I have a gallery with big ass thumbs, and a surfer loads it once... then the next day he comes back, it takes just as long to load. How do I make it so his cache or history will show those thumbs again.

just make sure you don't have this tag in your html

Don't be so cheap, let the guy load the same images each day!

If I have my options set in my browser to Check For Newer Version every time a page is checked, that is what it is going to do. And if I even suspect that you are trying to tell my browser what to do, you are never going to see me there again. Just like if you put a script in that changes my home page without my consent, I am going to stay away from your site forever.

Thanks. Money is not the issue. It's a matter of speed.
