Hello,

Ok, I wrote a function to blow up a thumbnail image by
replacing the thumbnail with an original size image. When you click
the thumbnail, a new window opens up with the size based on the
original image + 150 or 100 (height, width respectively). Well, I can
get the name of the original image perfectly but when it creates the
new window, it doesn't have the correct size of the image to make the
window. In fact, is makes a tiny window (possibly the size of the
thumbnail or it is using 0). I am not sure if maybe I should preload
the image or something so the browser has the correct original image
size? Well, here is the code:

var a,x;
var winHeight, winWidth;

// Finding the original image src from the thumb src
a = filename.indexOf('thumbs');
x = filename.substring(0,a) +
filename.substring(a+9,filename.length);


anImage.src = x;
winHeight = anImage.height+150;
winWidth = anImage.width+100;




I put in:

if (anImage.height < 1)
{
anImage.height = 500;
anImage.width = 320;
}

....between the x=filename and the anImage.src = x but that didn't work
either. Not sure what is happening. I suppose I should trace it a
bit. As I do that, anyone have any advice?

Thanks,

Josh
