copied!<p>In order to do that, you must read the EXIF information out of the JPEG file. You can either do that with <a href="http://php.net/exif" rel="noreferrer"><code>exif</code></a> PHP extension or with <a href="http://pel.sourceforge.net/" rel="noreferrer"><code>PEL</code></a>.</p> <p>Basically, you have to read the <code>Orientation</code> flag in the file. Here is an example using the <a href="http://php.net/exif" rel="noreferrer"><code>exif</code></a> PHP extension and <a href="http://wideimage.sourceforge.net/" rel="noreferrer"><code>WideImage</code></a> for image manipulation.</p> <pre><code><?php $exif = exif_read_data($filename); $ort = $exif['Orientation']; $image = WideImage::load($filename); // GD doesn't support EXIF, so all information is removed. $image->exifOrient($ort)->saveToFile($filename); class WideImage_Operation_ExifOrient { /** * Rotates and mirrors and image properly based on current orientation value * * @param WideImage_Image $img * @param int $orientation * @return WideImage_Image */ function execute($img, $orientation) { switch ($orientation) { case 2: return $img->mirror(); break; case 3: return $img->rotate(180); break; case 4: return $img->rotate(180)->mirror(); break; case 5: return $img->rotate(90)->mirror(); break; case 6: return $img->rotate(90); break; case 7: return $img->rotate(-90)->mirror(); break; case 8: return $img->rotate(-90); break; default: return $img->copy(); } } } </code></pre>
