anyone can help?

[pritaeas]

Can't see an error. Maybe the file upload had failed ?

Recap:
http://www.phpriot.com/articles/images-in-mysql

[almostbob]

header("Content-type: $contenttype"); 
header("Content-disposition: inline");

[papermusic]

header("Content-type: $contenttype"); 
header("Content-disposition: inline");

tried to add in the above into my image processor file, but doesn't works.

the image file is injected successfully into MySQL, i know its good cos i tried testing it with two images of different file size.
from phpymyadmin, i can see the longblob size.

<? $dbserver = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "em";
$dbconn = @mysql_connect($dbserver,$dbuser,$dbpass) or exit("SERVER Unavailable"); 
@mysql_select_db($dbname,$dbconn) or exit("DB Unavailable"); 
$sql = "SELECT image FROM em.testblob WHERE id =".$_GET["id"]; 
$result = @mysql_query($sql,$dbconn) or exit("QUERY FAILED!"); 
$image = @mysql_result($result,0,"imgdata"); 
$output = imagecreatefromstring($image);
header("Content-type: image/png"); 
header("Content-disposition: inline"); 
imagepng($output);
imagedestroy($ouput);
mysql_close($dbconn); ?>

not sure, untested, I only store file system
see aslo imagejpeg, imagegif, imagewbmp functions
if required test original content-type and output using the appropriate function

<? $dbserver = "localhost";
$dbuser  = "root";
$dbpass = "";
$dbname = "em";
$dbconn = @mysql_connect($dbserver,$dbuser,$dbpass) or exit ("SERVER Unavailable"); 
@mysql_select_db($dbname,$dbconn) or exit("DB Unavailable"); 
$sql = "SELECT image_type,image FROM em.testblob WHERE id =".$_GET["id"]; 
$result = @mysql_query($sql,$dbconn) or exit("QUERY FAILED!"); 
$image = @mysql_result($result,0,"imgdata"); 
$output = imagecreatefromstring($image);
header("Content-type: image/png"); 
header("Content-disposition: inline"); 
imagepng($output);
imagedestroy($ouput);
mysql_close($dbconn); ?>

this demo outputs everything as png.
if required check original content-type and output that image type, Im lazy

i got this thing to work on php4 before but some functions deprecated and it doesn't works now...duh

before i try your suggestion, can i clear some of my doubts?

sorry my noobiness, but does your method means i need to upload the image file in png format?

or does it convert the existing jpg image to output as png?

it outputs the image as png at the moment,
its a demo/ thought provoker not a solution yet
you could use the original content-type as a switch
--ignoring syntax-- I'm sleepy its midnight --

switch($image_type}
case 'image/gif':
 imagegif ();//etc
 break;
case 'image/jpeg' :
 imagejpeg ();//etc
 break;
case 'image/bmp': 
 imagewbmp ();//etc
 break;
