[RESOLVED] unique id for upload images? getting file extension

[phpjaco]

Hello

I have the following script that I created to enable uploading the same image, giving each image I upload a unique id. however the file contains no extension. Can anyone see what I did wrong here?

 function getExtension($typeOf) {
	     if ($typeOf == 'image/gif') {
		    return '.gif';
		 } else if ($typeOf == 'image/jpeg') {
		    return '.jpg';
		 } else if ($typeOf == 'image/png') {
		    return '.png';
		 } else if ($typeOf == 'image/vnd.wap.wbmp') {
		    return '.wbmp';
		 }
	   }

/**********************************************
		   ---   CREATE UNIQUE IDS FOR IMAGES ---
	    **********************************************/
		if ($_FILES['image_1']['name']) {
		    $uniqueImagePart1 = md5(date('h-s'));
			$uniqueImagePart1 = substr($uniqueImagePart1,0,5);

		$uniqueImagePart2 = md5($_FILES['image_1']['name']);
		$uniqueImagePart2 = substr($uniqueImagePart2,0,5);

		$uniqueImage1 = $uniqueImagePart1 . $uniqueImagePart2 . getExtension($_FILES['image_1']['type']);
		//echo '<br><br>'.$uniqueImage1;

when i echo the $uniqueImage1 I see the file but when I copy it there is no extension?

Here is my copy script

  if (!empty($_FILES['image_1']['name'])) {
		     copy ($_FILES['image_1']['tmp_name'],'articles/'.$uniqueImage1);
		   }

any help would be appreciated. Stangely enough the image show up in the browser no problem however contains no extension?

looks like it solved. think page was just not refreshing because it's in a frameset and modified mime type to be image/pjpeg instead of image/jpeg
