Photo Upload getimagesize() warning - filename cannot be empty

I've run into a conundrum and was wondering if anyone might be able to give me a straight answer. So I built a photo upload script using PHP/MySQL. Within the script photos are re-sized and given a temporary name while being uploaded. I tested it using several pictures (file size 220 KB | 960 x 720) and everything was working just fine. Then I attempted to upload several pictures from my digital camera (file size 2.47 MB | 3000 x 4000) and all of a sudden I got this error: ``` Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in /php_parsers/photo_system.php on line 94 Warning: Cannot modify header information - headers already sent by (output started at /php_parsers/photo_system.php:94) in /php_parsers/photo_system.php on line 96 ``` I checked stackoverflow for a post with a similar issue and came upon one however it didn't seem to apply to the scenario I'm experiencing. Here is the applicable code for "photo_system.php". I have commented the offending lines 94 and 96. Any help/ideas you could give would be greatly appreciated! ``` <?php if (isset($_FILES["photo"]["name"]) && isset($_POST["gallery"])){ $sql = "SELECT COUNT(id) FROM photos WHERE user='$log_username'"; $query = mysqli_query($db_conx, $sql); $row = mysqli_fetch_row($query); if($row[0] > 79){ header("location: ../message.php?msg=The system allows only 80 pictures total"); exit(); } $gallery = preg_replace('#[^a-z 0-9,]#i', '', $_POST["gallery"]); $fileName = $_FILES["photo"]["name"]; $fileTmpLoc = $_FILES["photo"]["tmp_name"]; $fileType = $_FILES["photo"]["type"]; $fileSize = $_FILES["photo"]["size"]; $fileErrorMsg = $_FILES["photo"]["error"]; $kaboom = explode(".", $fileName); $fileExt = end($kaboom); $db_file_name = date("DMjGisY")."".rand(1000,9999).".".$fileExt; // WedFeb272120452013RAND.jpg list($width, $height) = getimagesize($fileTmpLoc); //Offending Line 94 if($width < 10 || $height < 10){ header("location: ../message.php?msg=ERROR: That image has no dimensions"); //Offending Line 96 exit(); } if($fileSize > 4194304) { header("location: ../message.php?msg=ERROR: Your image file was larger than 4mb"); exit(); } else if (!preg_match("/\.(gif|jpg|png)$/i", $fileName) ) { header("location: ../message.php?msg=ERROR: Your image file was not jpg, gif or png type"); exit(); } else if ($fileErrorMsg == 1) { header("location: ../message.php?msg=ERROR: An unknown error occurred"); exit(); } $moveResult = move_uploaded_file($fileTmpLoc, "../user/$log_username/$db_file_name"); if ($moveResult != true) { header("location: ../message.php?msg=ERROR: File upload failed"); exit(); } include_once("../php_includes/image_resize.php"); $wmax = 800; $hmax = 600; if($width > $wmax || $height > $hmax){ $target_file = "../user/$log_username/$db_file_name"; $resized_file = "../user/$log_username/$db_file_name"; img_resize($target_file, $resized_file, $wmax, $hmax, $fileExt); } $sql = "INSERT INTO photos(user, gallery, filename, uploaddate) VALUES ('$log_username','$gallery','$db_file_name',now())"; $query = mysqli_query($db_conx, $sql); mysqli_close($db_conx); header("location: ../photos.php?u=$log_username"); exit(); } ?><?php if (isset($_POST["delete"]) && $_POST["id"] != ""){ $id = preg_replace('#[^0-9]#', '', $_POST["id"]); $query = mysqli_query($db_conx, "SELECT user, filename FROM photos WHERE id='$id' LIMIT 1"); $row = mysqli_fetch_row($query); $user = $row[0]; $filename = $row[1]; if($user == $log_username){ $picurl = "../user/$log_username/$filename"; if (file_exists($picurl)) { unlink($picurl); $sql = "DELETE FROM photos WHERE id='$id' LIMIT 1"; $query = mysqli_query($db_conx, $sql); } } mysqli_close($db_conx); echo "deleted_ok"; exit(); } ?> ```
