BLOB to GD resize/save out

[knowj]

I am currently trying to convert blobs within my database into files using the GD image library.

How would I go about creating the temp file to pass through to the GD library?

I have solved this issue using this technique:

$temp = tempnam("tmp/", "IMG_");
		$handle = fopen($temp, "w+");
		fwrite($handle, $row['front_img']);
		$image = new image($temp, constants::UPLOADDIR_PRODUCTS);
		$thumb = $url.$image->create_image('thumb');

	$image = new image($temp, constants::UPLOADDIR_PRODUCTS);
	$img = $url.$image->create_image('normal');

	$image = new image($temp, constants::UPLOADDIR_PRODUCTS);
	$detail = $url.$image->create_image('detail');

	if ($products->saveimages($row['id'], $thumb, $img, $detail, 'front'))
		{
			echo 'front saved for '.$row['id']."<br/>\n";
		}
	fclose($handle); // this removes the file
	unset($thumb, $img, $detail);
