javascript for a Popup from text and images?

[ezracomm]

Hi, I'm a novice so go slow with me...I'm looking for some javascript that will create a popup window from both text and images (and I need to be able to control the size of the popup).

I already have the following code, and if you can help me figure it out I don't need new code...but the problem I'm having is that it creates a window 20 px bigger than the image (the javascript 3/4 the way down that says " width = image_width + 20;
heigth = image_height + 20;" seems to be the correct element to change, but when I change each "20" to "1", it only affects the right and bottom sides of the pop up - that is, the image still has space around it on the left and top sides in the new pop up window.

This is the code I put in my header:

<script language="JavaScript" type="text/JavaScript">
<!--
function MM_reloadPage(init) { //reloads the window if Nav4 resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);
// -->

function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}

function MM_preloadImages() { //v3.0
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];}}
}

function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}

function image_open(image_loc,image_height,image_width)
{
var var_image = new Image();
var_image.src = image_loc;
width = image_width + 20;
heigth = image_height + 20;
str_style= "\" width="+width+",height="+heigth+"\"";
window.open(var_image.src,"myImage",str_style);

}
//-->
</script>





This is the code I use for my initial image and the popup that comes from that image:

<img src="../../images/picture_small.jpg" width="125" height="125" onclick="image_open('../../images/picture_large.jpg',250,400)">





Any help from you gurus? I have a feeling it's something really simple that I'm just missing...Thanks!
