D you mean how do you specify the height and width of an image so the page, as it loads, knows how to place the text? If so the html syntax is:

<IMG SRC="/path/to/image" HEIGHT="48" WIDTH="48" ALT="My Image">

The 48 is in pixels.

A nice link is

I mean... you know how the html loads first and then it takes time to load the pictures after... and for me (on a 24k connection) it takes forever to load the pictures. I'd like for the pictures to be preloaded so everythign loads at once, i know it will take just as long to load but id b a nice feature. if you know what i mean... im not a very good explainer.

in javascript it is....

Code
<HEAD>

<SCRIPT language="JavaScript">

Image1= new Image(200,200)
Image1.src = "image.gif"

Image2= new Image(340,200)
Image2.src = "coolpic.jpg"

</SCRIPT>

</HEAD>
I think thats pretty much self explanitory. The variable name you use is irrelevant because you don't use that to call the image. You still put the image on your page like normal, this code just brings it into the cache before hand for a fast load. Think thats what you wanted.

I do mine in an extremely complex and dynamic manner. If you are doing yours dynamically as well. You may want to think about doing something like this.
Create a javascript function that looks similar to this.
Code
function MM_preloadImages() { 
  var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
    var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
    if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
That is my javascript function. Then I proceed to call it like this.

Code
<body onLoad="MM_preloadImages('image1.jpg','image2.jpg','image3.jpg');"
Doing this makes it really easy to dynamically specify all the images you are going to need.

For mine? You'd just do what BackSlash did up there at first with the head and javascript tags. Then the body part would go with the body tag.

Oo. Good call. I didn't do the javascript. I do the perl that lies behind it.
