Image creation using php
<p>Am trying to create a video clip using .jpg images and ffmpeg, am creating .jpg images as below:</p>

<pre><code>  $str=$_REQUEST['data_array'];//gets the base64 encoded image data;  
  $count =$_REQUEST['count'];//gets number of images i've to create;
  $edited_str=substr($str,23,strlen($str)-1);// 
  $edited_str=base64_decode($edited_str);  
  $f=fopen("Images/temp".$count.".jpg","w");//am creating temp.jpg file
  fwrite($f,$edited_str);//placing my decoded data into file
  fclose($f); 
</code></pre>

<p>are the images am creating above different from normal .jpg images? </p>
