    copied!<p>I have a code that dinamically resizes an image and sends it to the browser.</p> <p>But it doesn't work properly... only if I ask it to output the image to a file instead of the browser.</p> <p>I don't think the problem is my code, because this problem <em>only occurs on the real server</em>; in my computer its working perfectly.</p> <p>Code:</p> <pre><code>$img = $_GET['img']; ini_set('allow_url_fopen', 'on'); $info = getimagesize($img); header('Content-type: '.image_type_to_mime_type($info[2])); Fotos::redimensiona($img, null, Fotos::MINIGAL_WIDTH, Fotos::MINIGAL_HEIGHT, false); </code></pre> <p>Fotos::redimensiona():</p> <pre><code>//[...] a whole bunch of code calculating dimensions, they just works // $funcImage is like 'imagejpeg'/'imagepng'/'imagegif', depends on file if ($arquivo) { $funcImage($thumb, "$final.$ext"); return "$final.$ext"; } else { $funcImage($thumb); } </code></pre> <p>Remember: it <strong>works</strong> on local development, but doesn't on remote web server.</p> <p><strong>[EDIT]</strong><br> if I comment the <code>header</code> line, the binary code is printed; and this code changes when i change the original image, as expected.<br> But with the <code>header</code> Firefox shows me the URL of the page (like <code>http://www.sabianoar.com.br/novosabia/inc/phpImg.php?img=awful_escaped_long_path.jpeg</code>), and if I do <code>CTRL+I</code> it tells me it is an JPEG of 0x0 size, and like 10kb.<br> Opera shows me an empty image, as it would do if I had placed an <code>&lt;img&gt;</code> with the wrong <code>src</code>, i.e.</p> <p><strong>[EDIT2]</strong> EyeOfGnome says "Not a JPEG file: starts with 0xef 0xbb" when I try to save and then open the output (it saves to a .jpeg file normally).</p>
