    <p>Am using the very handy SimpleImage PHP class for resizing images, and have run into the following problem:</p> <p>While test uploading various images, certain pictures were being uploaded but not resized. Upon investigation, it appears that the actual dimensions of the image were the cause of the problem (not the file size). A 5M image would upload and resize, whereas a 1.9M image would not. The difference was the latter was 4000 X 3000 - larger dimensions than the other. I resized the succeful image to be sure, and the same failure occured.</p> <p>This is a silent failure, no error messages are being generated.</p> <p>I am using the exact SimpleImage class as shown <a href="http://www.white-hat-web-design.co.uk/blog/resizing-images-with-php/" rel="nofollow">here</a></p> <p>I am using it in conjunction with Uploadify, as shown below. At the moment, I'm just trying to get a flat conversion to a 200px high image. Any help in solving this would be greatly appreciated - do I need to incrementally resize, or what is the best course to follow?</p> <pre><code>&lt;?php session_id($_REQUEST['sID']); session_start(); require_once '../config.php'; $target_dir = $_SERVER['DOCUMENT_ROOT'].GAL_DIR.$_POST['target_dir']; if (!empty($_FILES)) { require_once 'SimpleImage.php'; $file_parts = pathinfo($_FILES['Filedata']['name']); $name = preg_replace("/[^A-ZÀ-ÿ0-9._-]/i", " ",$file_parts['filename']); /* Just some record keeping... $text = "txtrec.txt"; $att = $target_dir."txtrec.txt"; $record= "TIME: ".date('Y-m-d H:i:s')."\n"; $record.= "IP: ".$_SERVER['REMOTE_ADDR']."\n"; $record.= "DATA ARRAY: ". implode(",",$_FILES['Filedata'])."\n"; $record.= "NAME: ".$_FILES["Filedata"]["name"]."\n"; //file-name.ext $record.= "TYPE: ".$_FILES["Filedata"]["type"]."\n"; //application/octet $record.= "SIZE: ".$_FILES["Filedata"]["size"]."\n"; //bit size $record.= "TMP_NAME: ".$_FILES["Filedata"]["tmp_name"]."\n"; //tmp storage name $record.= "BASENAME: ".$file_parts['basename'] ."\n"; //file-name.ext $record.= "EXTENSION: ".$file_parts['extension'] ."\n"; //ext (no dot) $record.= "FILENAME: ".$file_parts['filename'] ."\n"; //file-name (no dot/ext) $record.= "DOCUMENT_ROOT: ".$_SERVER['DOCUMENT_ROOT']."\n"; $record.= "TARGET_DIR: ".$target_dir ."\n"; //path to gallery dir (with closing slash) $record.= "TMP_DIR: ".$target_dir.'tmp/'."\r\r\n"; $fh = fopen($text, 'a') or die("can't open file"); fwrite($fh, $record); fclose($fh); $fh = fopen($att, 'a') or die("can't open att file"); fwrite($fh, $record); fclose($fh); */ // Validate the file type $ok = FALSE; $ok_types = array('jpg','jpeg','gif','png'); $file_ext = strtolower($file_parts['extension']); if (in_array($file_ext,$ok_types)) { $ok = TRUE; } if($ok) { $fileName = $name.'.'.$file_parts['extension']; array_push($_SESSION['files'],$fileName); $tmp_file=$target_dir.'tmp/'.$name.'.'.$file_parts['extension']; $target_file=$target_dir.$name.'.'.$file_parts['extension']; move_uploaded_file($_FILES["Filedata"]["tmp_name"],$tmp_file); list($width, $height, $type, $attr) = getimagesize($tmp_file); $dimensions = $width.'

    1. COHere is one thing you could check: the SimpleImage library uses the GD function imagecreatefromjpeg (or the corresponding format equivalent), which fails silently with a false return. Check what a direct imagecreatefromjpeg on your image returns.

    2. COThis may be the problem, as alluded to by Jack below. Running this function on its own returns the error `Allowed Memory size exhausted...` Pumping the memory limit at the top of the script is not working however, seemingly not changing the default (still returning `tried to allocate 16000 bytes`). Any ideas?

    3. COThe other [SO question](http://stackoverflow.com/questions/6991602/fatal-error-allowed-memory-size) I read on this said the problem was occurring because he was not destroying the image objects afterwards to free up memory (they have an imagedestroy function). You aren't using a loop are you?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
