"Larger Image" pop up is same size as Image

[Indigo Nest]

When I click on "Larger Image", the pop up is the same size as the original image. I followed a post that I saw here and edit the file jscript_main.php:

<script language="javascript" type="text/javascript"><!--
function popupWindow(url) {
window.open(url,'popupWindow','toolbar=no,location=no,directories=no,status=no,m enubar=no,scrollbars=no,resizable=yes,copyhistory=no,width=400,height=550,screen X=150,screenY=150,top=150,left=150')
}
function popupWindowPrice(url) {
window.open(url,'popupWindow','toolbar=no,location=no,directories=no,status=no,m enubar=no,scrollbars=yes,resizable=yes,copyhistory=no,width=400,height=550,scree nX=150,screenY=150,top=150,left=150')
}
//--></script>

No changes were noted. The original image size is 400x600, so that's not an issue. Not sure what to do at this point. I have the images in the "Image" folder as well as the "Large" sub folder. Any Suggestions?

Do you have 3 different size images?

For example:
images/image.jpg
images/medium/image_med.jpg
images/large/image_lrg.jpg

I haven't edited the files you referenced but I am having the same problem. The larger image is the same size. I followed all the tutorials but still haven't been able to solve the issue.

I finally figured it out. When I was downloading the images from my supplier, I was downloading the thumbnails instead of the actual images
