Código PHP:
<form action="<?php echo $editFormAction; ?>" method="post" enctype="multipart/form-data" name="form1">
<input name="img" type="file" class="todopanel" id="img" enctype="multipart/form-data" />
<input name="img" type="file" class="todopanel" id="img2" enctype="multipart/form-data" />
<input name="img" type="file" class="todopanel" id="banner" enctype="multipart/form-data" /></form>
asi está
