If I remember correctly, it's because when you submit via an image, instead of getting one parameter called "logon" in the request, you actually get two params called "logon.x" and "logon.y" which contain the coordinates at which you clicked on the image - there will *not* be a request param called "logon". So just check for "logon.x" instead of logon.
It's ages since I used this, so I hope I've remembered it right! Hope this helps.
