I'm having trouble to get the following code to upload large images. It works great with images less than 1000px by 1000px, but breaks on anything bigger. Any help/ideas greatly appreciated. Note: I have tried increasing the '$memoryNeeded>=10000000' to '7700000000' but still no joy.\[code\]if (!$error && is_uploaded_file($_FILES['galleryFile']['tmp_name'])) { $format = strtolower(substr(strrchr($_FILES['galleryFile']['name'],"."),1)); $str = strtolower(trim($_FILES['galleryFile']['name'])); $str = preg_replace('/[^a-z0-9-]/', '-', $str); $str = preg_replace('/-+/', "-", $str); $filename=$str.'.'.$format; $uploadGallery=$origFileDir.$filename; foreach ($allowedImgFormats as $key => $value) { $value=http://stackoverflow.com/questions/3678561/=$format ? $imgFormatOK='1' : NULL; } $imgFormatOK=='0' ? $error='You are attempting to upload an image with an invalid format!<br />Please only upload images with ".gif", ".jpg" or ".jpeg" extensions.' : NULL; if (!$error && move_uploaded_file($_FILES['galleryFile']['tmp_name'], $uploadGallery)){ $galleryW='944'; $galleryH='733'; $galleryInfo = getimagesize($uploadGallery); $memoryNeeded = Round(($galleryInfo[0] * $galleryInfo[1] * $galleryInfo['bits'] * $galleryInfo['channels'] / 8 + Pow(2, 16)) * 1.65); if ($memoryNeeded>=10000000) { unlink($uploadGallery); $error='The chosen image is too large to process.<br />Please upload a smaller image (lower dimensions and/or resolution).'; } else { list($wOrig, $hOrig) = getimagesize($uploadGallery); $ratio_orig = $wOrig/$hOrig; if ($wOrig > $galleryW) { $galleryW = $galleryH*$ratio_orig; $galleryH = $galleryW/$ratio_orig; } else { $galleryW=$wOrig; $galleryH=$hOrig; } if ($galleryH > $galleryH) { $galleryH = $galleryW*$ratio_orig; $galleryW = $galleryH/$ratio_orig; } $galleryP = imagecreatetruecolor($galleryW, $galleryH); switch($format) { case 'gif' : $thisGallery = imagecreatefromgif($uploadGallery); break; case 'jpg' : $thisGallery = imagecreatefromjpeg($uploadGallery); break; } imagecopyresampled($galleryP, $thisGallery, 0, 0, 0, 0, $galleryW, $galleryH, $wOrig, $hOrig); switch($format) { case 'gif' : $createGallery=imagegif($galleryP, $galleryFileDir.$filename, 88); break; case 'jpg' : $createGallery=imagejpeg($galleryP, $galleryFileDir.$filename, 88); break; } imagedestroy($galleryP); imagedestroy($thisGallery); unlink($uploadGallery); if (!$createGallery) { $error='The chosen image failed to transfer correctly.<br />Please try again, or attempt to upload an alternative image.'; file_exists($galleryFileDir.'/'.$filename) ? unlink($galleryFileDir.'/'.$filename) : NULL; } else { $_POST['imagename']=$filename; mysql_query("INSERT INTO isgallery(imagename, assoc_object) VALUES('".$_POST['imagename']."', '".$_POST['id']."')"); } } } else { !$error ? $error='The chosen image failed to upload correctly.<br />Please try again, or attempt to upload an alternative image.' : NULL; file_exists($uploadGallery) ? unlink($uploadGallery) : NULL; } }\[/code\]
