Image swap in IE

I am doing an image swap using I've tried using my own code and also the
Dreamweaver behavior. Works fine in FF but when i check it in IE the orginal
Image disappears and I'm left with a blank space. However... when i right clcik
and choose show picture, the image appears.

Has anyone else ever come across this?

Thanks,
Jeremy

OK Riddle me this Batman(and when i say Batman I mean Murry)...

I am using text links to trigger the image swap.

When i use this it works localy but not on the live server

<a href="javascript:void(0)" onclick="changeView('<?php echo
$row_rs_mailer['mailerImgPrefix'];?>');">1</a>


When i use this
<a href="#" onclick="changeView('<?php echo
$row_rs_mailer['mailerImgPrefix'];?>');">1</a>

Things that make you go hmmmm...
