Change url text dynamically from text file

Question

I need to use a text file created from a form to rewrite the
links on my main page. Can I put some kind of javascript in the
href so when the page loads it'll rewrite the link to point to
"newpic1.jpg" where newpic1.jpg is one of the items from the text
file created by my form?
Please help, this has got me really stuck. All help greatly
appreciated!!!

that is the difficulty with a text file...
if the links are to remain only for a session, you can set a
session var
a simplified method - using PHP - would be:
1. form
<form id="form1" name="form1" method="post"
action="process_form.php">
<label for="selectimg">Select Image:</label>
<select name="selectimg1" id="selectimg">
<option value="img_blue.gif">Image blue</option>
<option value="img_red.gif">image red</option>
</select>
</form>
2. process_form.php
<?php
$_SESSION['img_array']['img1']=$_POST['selectimg1'];
?>
3. wherever the image needs to be displayed:
<img src="/images/<?php echo
$_SESSION['img_array']['img1']; ?>" />
Please be advised that this is a very simplified version and
that if you
do use something like this you have to first clean up
whatever the form
submits. NEVER trust user input - it could be malicious
code...
