I'm trying to display image in php page from a SQL database. When i try i see: ÿØÿàJFIFHHÿáWExifMM* instead of the image that I expected. Please Help me to read or display this as an image.

Most likely you're not outputting a content-type header, so the server and/or browser are assuming you're ouputting plain text, and displaying it as such:

<?php

// database stuff here

header('Content-type: image/jpeg');
echo $jpgdata;

should fix it up.

I belive a good solution would be load the image from a string (you table column for instance), and as you don't know the type, you could force GD to print a specific type (in this case JPEG), as follows:

<?
 ...
 $data = $row["line"];

 $new_im = imagecreatefromstring($data)

 Header("Content-Type: image/jpeg");
 Header("Content-Description: PHP Generated Image");

 imagejpeg($new_im);
?>
