    hi - i am trying to understand your request. if it could be stated more clearly, it will be easier to help you.

    if you want to pass a value from a form on one page to something on another page, this can easily be accomplished by using a cookie to pass a form value from one page to another


    are you talking about the images on page 1 ? there doesn't need to be any refresh. you can add text to a selected image many different ways, all without going back to the server. one easy way: each image's name is passed to the click function . a simple function can fill a text box with the name of a clicked/selected image.
    example:
    
<head>
<script type="text/javascript">
function revealName(nam){
document.getElementById("textbox").value=nam	
}
</script>
</head>

<body>
<input type="text" id="textbox" />
<img src="pic1.jpg" name="picture one" onclick="revealName('picture one')" />
<img src="pic2.jpg" name="image number 2" onclick="revealName('image number two')" />

</body>
    Code (markup):
    hope i understood your request correctly, and if so, hope this helps

    Probably showing some of your script here,
    would help us understand better.

    My guess is that it's a process before form submission?

    So your popup page_2 look like:
    <a href="javascript:void(0)" onclick="report(this)"><img src="water.jpg" style="background-color:#faa;" alt="water"/></a>
<a href="javascript:void(0)" onclick="report(this)"><img src="fire.jpg" style="background-color:#afa;" alt="fire"/></a>
<a href="javascript:void(0)" onclick="report(this)"><img src="soil.jpg" style="background-color:#aaf;" alt="soil"/></a>
    HTML:
    To report to opener page, this popup uses report() function:
    <script type="text/javascript">
  function report(a){
    opener.document.getElementById("img_name").value = a.childNodes[0].src;
  }
</script>
    Code (markup):
    where img_name is the id of textbox on opener page_1:
    <form>
  <input id="img_name" type="text" />
</form>
    HTML:
    Remember though, that not all browsers like popup window,
    and your popup would be opened in browsers tab.
    Opening an iframe is a better,
    but these two require same domain rule to work.

    Just a layer div, is much better.
