you can use JavaScript and put the picture in a link:

<a href="javascript:void(document.myform.submit())"><img src="source_here"></a>

or you can do this:

<INPUT TYPE="image" NAME="submit" src="source_here" alt="Submit">

I tried the

<INPUT TYPE="image" NAME="submit" src="source_here" alt="Submit">

however my form action =$PHP_SELF

and then this is after

if($submit)
{
call function
}

It will submit however it will not pass the "name" so that the if statement becomes true.

You can get around that by adding a hidden element, like <input type="hidden" name="beenSubmitted" value="submitted"> and changing your if statement to if ($beenSubmitted == "submitted")

You might have to use $_REQUEST['beenSubmitted'] depending on how you have global variables set.

When you use an image as a submit button, PHP passes the X and Y coordinates in the $_POST args.  So, to see if the form was submitted using a given images, you should check:

if (isset($_REQUEST['submit_x'])) {
    // call function
}
