Unlinking an image from a website

I have an update form and one of the options to be update are the images
<input name="image1" type="file" class="style81" id="image1" size="20" /> thats a sample of the  file field.
Lets say a user added an image when they were adding a product and now with the update of that product they want to unlink a specific image - remove it from the website
how can it be done?
below is my update statement, generated with dreamweaver
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
  $updateSQL = sprintf("UPDATE enginesubcategory SET make=%s, model=%s, `year`=%s, engine=%s, cc=%s, cyl=%s, type=%s, fuel=%s, thumbnail=IFNULL(%s,thumbnail), product=%s, comments=%s, commentsExtras=%s, image1=IFNULL(%s,image1), image2=IFNULL(%s,image2), image3=IFNULL(%s,image3), image4=IFNULL(%s,image4), image5=IFNULL(%s,image5), image6=IFNULL(%s,image6), image7=IFNULL(%s,image7), image8=IFNULL(%s,image8), image9=IFNULL(%s,image9), image10=IFNULL(%s,image10), image1Big=IFNULL(%s,image1Big), image2Big=IFNULL(%s,image2Big), image3Big=IFNULL(%s,image3Big), image4Big=IFNULL(%s,image4Big), image5Big=IFNULL(%s,image5Big), image6Big=IFNULL(%s,image6Big), image7Big=IFNULL(%s,image7Big), image8Big=IFNULL(%s,image8Big), image9Big=IFNULL(%s,image9Big), image10Big=IFNULL(%s,image10Big) WHERE id=%s",

OK is the image stored on disk? If so then you simply have to get the path and the filename and use the "unlink" command

// image name would probably need to be retrieved from the database
chmod("$path/$image"], 0755); // make sure you have permissions to remove it
unlink("$path/$image"); // removes it

If you need more clarification let me know.

As i understood, you have 10 images within an one record. When you want to delete image from the server, delete it from Form variables, for example, let's say you want to delete image1:
<input name="image1" type="file" class="style81" id="image1" size="20" />
Free this from value in the HTML form by mean javascript:

document.getElementById("image1").value = "";

When you submit form, $_FILES['image1'] variable on the server side will be empty. According to this you can identify which image file is going to be deleted.
