Header Content Type Image Png In Php

vote favorite I am having hard time with php headers, i'm trying to create any kind of image in my browser without saving it in a file, but no matter what i do i can't get it working. So for example if i use this basic example from php manual: $im = imagecreate(100, 100); header('Content-Type: image/png'); imagepng($im); imagedestroy($im); It would set correct header and even output that icon which imagepng not working u get when image is not found. Also i use xampp which have GD enabled, here is my phpinfo GD part: GD Support enabled GD Version bundled (2.0.34 compatible) FreeType Support enabled FreeType Linkage with freetype FreeType Version 2.4.3 GIF Read Support enabled GIF Create Support enabled JPEG Support enabled libJPEG Version 6b PNG Support enabled libPNG Version 1.2.46 WBMP Support enabled XBM Support enabled Is my code is wrong or do i need to configure something? php gd share|improve this question edited Mar 23 '12 at 18:58 Juicy Scripter 20.2k44369 asked Feb 29 '12 at 14:25 Linas 1,20584591 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted You should not only create the image but also fill it some way: error_reporting(E_ALL); ini_set('display_errors', 1); $im = imagecreate(100, 100) or die("Cannot Initialize new GD image stream"); $background_color = imagecolorallocate($im, 0, 0, 0); header('Content-Type: image/png'); imagepng($im); imagedestroy($im); share|improve this answer edited Feb 29 '12 at 14:51 answered Feb 29 '12 at 14:33 Juicy Scripter 20.2k44369 Still doesn't work, i've tried to look at it with firefox, and this is what i got: The image “http://localhost/test/” cannot be displayed, because it contains errors. –Linas Feb 29 '12 at 14:36

So anything output after that would have to be a binary PNG. You can't then place HTML and expect that to work echo ''; This works because you're base64 encoding your image (translates binary into text), outputting that to the browser and then telling your browser to interpret it as base64. If you want to output the raw binary data you have to rearrange the order. So here's your HTML Now you'll note the src points to a PHP file. That's because we're going to have that PHP file return an image. Here's what image.php would look like //Your query here $row = mysqli_fetch_assoc($result); header("Content-type: image/png"); echo $row['image1']; This works because the browser will call the PHP file, expecting an image.
