[jQuery] refresh image?

[jQuery] refresh image?


Hi, after sending a form, I would like to reload the form in order to
send a new message.
Therefore I was resetting the old form, but I need to call a new
captch image.
It's currently like this:
<img src="inc/captcha/captcha.php" id"="captcha" alt="" border="0"
style="float:left;" />
I thought I coud re-load it with:
$("#captcha").attr("src").replaceWith("inc/captcha/captcha.php");
But this way I don't get a new call... to generate a new image and
with it connected a new session entry for the captcha code.
What can I do to create a real call to the file? Any ideas?
Thanks
Heidi
