You could use an INPUT tag with style="display:non", and have your function change style to "display:inline".

You need a fileUploadControl which is basicaly an form input field of type=file and you need to hide it. Then you call the fileUploadControl click()  event on Image onclick event.
Like this:

<html>
<head>
<title>Zvonko &#42;</title>
</head>
<body>
<form name="myForm" enctype="multipart/form-data" method="post">
<input type="file" name="myFile" style="display:none;" onChange="document.getElementById('fName').innerHTML=this.value;this.form.Upload.style.display='';">
<span id="fName"></span>
<input type="submit" name="Upload" style="display:none;" value="Upload">
</form>
<img src="filesel.gif" onClick="document.forms[0].myFile.click()">
</body>
</html>


You see?

Sorry, it seams the FireFox is more restrictive with FileUpload features then IE.
A second observation that I had made with FileUpload is that as soon as you access by script any feature of the FileUpload object is the file not uploaded to server.
Sorry, but that all is security features of the browser.
I do not know how to upload a file by clicking on an image in FireFox.
By the way, calling click() of FileUploadControl does not throw an exception or error in FireFox. It simply does not do anything.
