Hi,
Output the correct headers before you output the image
ie
header("Content-type: image/jpeg");
imagejpeg($dst_img, '', 50);
Remove all print statements from this code. You cannot output anything but
the headers and the image itself.
Use imagecopyresampled if you can. It gives much better quality.
Then to output the image from another script (not within test.php) use this:
<img src="test.php">
