BTW, here is the code for my admin page that has the browse file field.

PHP Code:

// Add Sponsor
if ($_REQUEST['do'] == 'add')
{
print_form_header("sponsors", "saved", "false", "true", "add_entry", "90%", "", "true", "post");
print_table_header("Add Sponsor");

echo '<tr><td class="alt2">Image File</td><td class="alt2"><input type="file" name="img_file" /></td></tr>';
print_submit_row("Add Sponsor");
print_table_footer();  
}
