Are these steps correct and standard way to upload images into a table?

["Zhidian Du" <duzhidian@xxxxxxxxxxx>]

I check the posts about uploading images from browser.  No one give me a 
whole procedure how to do it.  My friend told me I can upload binary/image 
file using following steps:

I want to know are these steps standard steps that insert images into a 
table?


Step 1 upload it
<FORM METHOD=POST ACTION="" enctype="multipart/form-data">
<tr><td>upload </TD><TD><input type="file" name="pic" 
size=40></td></tr></form>

<?
	if($pic_name != '')
	{
	$len = strlen($pic_name)-4;
	$ext = substr($pic_name,$len);
	$ext = strtolower($ext);

	$File="/www/pics/test".$ext;
	exec("cp $pic $File");
	}


?>

Step 2 Read it
$fd = fopen($img_name, "r");
       while ($post_file = fread($fd, 4096))
       {
        $filestuff .= $post_file;
       }
       fclose($fd);


Step 3 insert or update into the table using insert or update

Are these steps correct or the standard way to upload images into a table?

Thanks.
