Blocking users by IP
Blocking bad bots and site rippers (aka offline browsers)
Preventing hot linking of your images and other file types

It's straining at a gnat to perceive of those things being client side functions. If you don't see that, then you don't understand the paradigm well. Informing you of that might be distasteful to you, but it's not an insult. I do have some spare ones lying around, if you want one.

To clarify a little:

Javascript is a client-side language. This means that it is executed not by your web server, but by the people accessing your web server. The browser executes the Javascript, not the server, and Javascript can thus be turned off at will.

Because of this, Javascript cannot block IPs, prevent hotlinking or do any of the things you wish. It simply can't be done by a client-side language.

Some of the things you wish to do can be done server-side, such as banning IPs and preventing hotlinking (via the Referer header), but some cannot. You cannot prevent a person from downloading content from your site. If they can view your page, they can save it. It's as simple as that.

I suggest you find a web hosting company that supports .htaccess files and PHP. Hosting companies that support such are cheap and plentiful. You can get a host for as little as $12 (or �7, or �10) a year.

Not so broke that you can't afford a domain/hosting

Edit: And you're doing some truly creepy things on that page - reloading the window if netscape 4 resizes? Do you even know what Netscape 4?
