Question

i am displaying an image usign readfile() function of php

HMTL:

<img src='image.php?id=232'/>

PHP: image.php

<?php
   $id=$_GET["id"];
   if(image_view_allow($id)){
     $path=get_image_path($id);
     readfile($path);
   }else{
     readfile("images/not_allow.png");
   }

image_view_allow and get_image_path is two that i have defined to check validation and get path
I am doing this because i want show image only to the allow person.

Does this affect speed of downloading an image ?
what is normal(means direct path in src attribute of img tag) or trick that is shown above?

Answer 1

Just loading an image probably same,but it is always better if you handle images with php, because when you resize image with php you load the needed size. But with html you load the bigger size than you need and resize.
