from ISAPI's point of view there is no difference. But think of what happens from a CGI point of view, and i think this will answer your question: picture this simple html form:
when that form is submitted the Post data will be this: PhoneNumber=4535435&submit=Send Now picture this form:
when this form is submitted, the post data will be this: PhoneNumber=4535435&submit.x=45&submit.y=122 When you use an input type=image, their are two more form values entered, name.x and name.y which are the coordinates in which the image was submitted. Therefore, my guess it that your page is doing wierd stuff in decoding this input.
