How can you upload an image to MYSQL using php?

Question

Ok this is a joint thread with one of my other ones because no one else  was posting on it, so I did not get what I needed, so, How can you  upload an image to mysql so when some one logs on to my site, they see  or can upload there own avatar, now there are loads of problems with  this, 1) many people don't know how, 2) It's not every day you try to  encode a image into mysql, 3) Letting people upload images into mysql  can cause traffic problem with people trying to log in. So that's it.

Uploading images into MySQL is a bad idea, for more reasons than you mention. You should store the images in a directory on the server instead. But if you want to learn the hard way, here is the method:
The mysql data type must be blob.
The form enctype must be multipart, like this: enctype="multipart/form-data"
The form input field myst be type file, like this: <input type="file" name="upload"/>
Here is example code that prepares the variable $photodata to be inserted into the database.
  $uploadfile = $_FILES['upload']['tmp_name'];
  $photoname = $_FILES['upload']['name'];
  $uploadtype = $_FILES['upload']['type'];
  if ($uploadfile != "") {
$tempfile = fopen($uploadfile, 'rb');
$filesize=filesize($uploadfile);
$width=getimagesize($uploadfile);
$widthx=$width[0];
$heightx=$width[1];
if (($widthx > 102) or (heightx > 135)){
$image_too_big = " but the image size was too large and was not submitted.";
} else {
$photodata = fread($tempfile, filesize($uploadfile));
$photodata = addslashes($photodata);
