Well the problem with you solution is I have to redo whatever I do to make the image which seems inefficient.

Here's my code from a wider view:

(Toggle Plain Text)

class Bundle{
  var $something, $or, $other, $image, $image_type;
  //constructor
  function Bundle($a){
   if (is_array($a)){
       foreach ($a as $k=>$v){
         $this->$k = $v;
       }
   elsif (is_int($a)){
      //get the object from database
   }
  }
  //class method
  function show(){
    echo "<h1>Hi There". $this->something."</h1>";
    echo "<img src="image.php?bundle=".$this->something";
  }
}
///// end class
image.php
$i = $_GET['bundle']
$bundle = new Bundle($i);
header ("Content-type: "$bundle->image_type);
echo($bundle->image);

The above works okay if I must to something like:

(Toggle Plain Text)

$b = new Bundle(7);
$b->show();

but I'm still stuck when I get the image from a form.

(Toggle Plain Text)

$something = $_POST['something'];
$or = $_POST['or'];
$other = $_POST['other'];
$type = $_FILES['image']['type'];
$image = fread(fopen($_FILES['image']['tmp_name'], "r"), $_FILES['image']['size'));
$a = array('something'=>$something,
               'or'=>$or,
               'other'=>$other,
               'image'=> $image,
              'image_type'=>$type);
$bundle = new Bundle($a);
$bundle->show();

won't work at all. So far as I can tell there is no way to make show work as I'd have to pass all the same info to image.php.

I suppose below could be a compromise:

(Toggle Plain Text)

class Bundle{
  var $something, $or, $other, $image, $image_type;
  //constructor
  function Bundle($a){
   if (is_array($a)){
       foreach ($a as $k=>$v){
         $this->$k = $v;
       }
   elsif (is_int($a)){
      //get the object from database
   }
  }
  //class method
  function show(){
    echo "<h1>Hi There". $this->something."</h1>";
    if (isset($this->image_file){
     echo "<img src=".$this->image_file.">";}
   else
    echo "<img src="image.php?bundle=".$this->something";
  }
}
///// end class
////from form
$something = $_POST['something'];
$or = $_POST['or'];
$other = $_POST['other'];
$type = $_FILES['image']['type'];
$image = fread(fopen($_FILES['image']['tmp_name'], "r"), $_FILES['image']['size'));
$image_file = temp_nam();
$i = fopen($image_file, "w");
fwrite($i, $image);

$a = array('something'=>$something,
               'or'=>$or,
               'other'=>$other,
               'image'=> $image,
              'image_type'=>$type,
               'image_file'=>$image_file);
$bundle = new Bundle($a);
$bundle->show();

so that a temp fil is writen if not from database.

I still say, there should be a way I can sen the raw data directly to a file.

I don't believe there is a way. The image needs its own header information.

Your uploads, do you store them in the database? If so, could you just get them from there?

Well...... yes.

There's two stages.
1) Creating them from a form and checking and proofing them before comitting them to the database.
For this stage I can make and refer to temp files.
2) once committed to DB I can use call the image from the database.
A neat tidyness is that I can call "unlink" on the temp files at precisely the same time as committing them to the database.

It's a fix. It'll work.

I don't really like it, though. Seems redundant. But it definately will work.
