<tr>
<td width="150" class="label">Description</td>
<td class="content"> <textarea name="mtxDescription" cols="50" rows="4" class="box" id="mtxDescription"><?php echo $cat_description; ?></textarea></td>

<tr>
<td width="150" class="label">Image</td>
<td class="content">
<input name="file" type="file" id="file" class="box">
<?php
if ($cat_image != '') {
$image = 'images/' . $cat_image;
?>
<br>
<img src="<?php echo $image; ?>" width="211" height="140"> <a href="javascript:deleteImage(<?php echo $cat_id; ?>);">Delete
