I've had this happen on Firefox many times. I've attached images, clicked Preview and the images shows up as expected. Click submit and the image(s) are suddenly replaced with links. For example: http://www.setiusa.us/showthread.php...ll=1#post69506 and this one with 2 images: http://www.setiusa.us/showthread.php...ll=1#post69839
That's under 100kB of course. Over 100kB i get nothing.
