<input type="file" name="file1" id="f1">
<input type="submit">
</form>
</body>
</html>

Thanks in advance,

You do realize that this will work only when the browser is being displayed on the system housing the image file and will not work on any other system, right?

In any case, what's with the double-slashes?
