Thanks for your reply.  Unfortunately, I'm seeing that do_preview() is undefined. 

 

What I'm doing is providing an alternate Browse function, which allows the user to select images from a remote location.  Once they select an image, a call is made to the following custom function on tag_image.ascx:

 

 

function FileShareHandler(imgPath, width, height) {
    var inImageUrl      = document.getElementById("inp_src");
    var inImageWidth    = document.getElementById("inp_width");
    var inImageHeight    = document.getElementById("inp_height");
   
    inImageUrl.value    = imgPath;
    inImageWidth.value  = width;
    inImageHeight.value = height;
   
    do_preview();
}

 

Am I calling do_preview() incorrectly or is there a different method I should be using?
