My Lazy Flash Loader, Does it work correctly and behave accordingly?

Question

Version 1:

<style> 
embed {
display: none;
} 
</style> 

<script>

var p1 = 0;
var p2 = 1;
var amount = 0;
/* var counter = 0; */
$(window).scroll(function() {
/*if(counter % 2 === 0){  */
if($(window).scrollTop() &gt;= amount){
amount+=500; 
if(!($(&#39;embed&#39;).slice(p1,p2).show())){
$(window).unbind(&quot;scroll&quot;);
}
++p1;++p2;
}

/* }
++counter; */
});



</script>

Version 2:

<style> 
embed {
display: none;
} 
</style> 

<script>

var p1 = 0;
var p2 = 1;
/* var counter = 0; */
$(window).scroll(function() {
/*if(counter % 2 === 0){  */

if(!($(&#39;embed&#39;).slice(p1,p2).show())){
$(window).unbind(&quot;scroll&quot;);
}
++p1;++p2;
/* }
++counter; */
});



</script>

My attempts at making a Lazy flash loader (a flash loader which loads on demand), I am really proud of myself since I'm not a programmer. I came up with my own version after seeing that lazyLoader didn't do what I wanted, (frankly too complex for me too, lol). I use this on my blogger blog which loads zazzle gallery widgets and I think it's improved the loading times. I use version 2 without the scroll amount control.

My questions are: 1. is it effective? I think the scroll amount control would improve things only when it gets larder. 2. How does my blog load? Do you see any improvements? 3. Do I use unbind accurately? Is it really unbinding? 4. Does my not expression really stop the slicing when it returns out of bounds? 5. What do you think? How can I improve it? :)

Thanks you, much appreciated for any constructive feedback :)
