note 62935 added to function.imagejpeg

I'm experiencing weird behaviour with imagejpeg() function. I'm trying to upload a jpg image with a form, check wether it does not exceed 600px width, and store it in a mysql database: <?php // Get rid of magic_quotes function getsafe($tmp) { if (!get_magic_quotes_gpc()) return $tmp; else return stripslashes($tmp); } // Read the image $file = imagecreatefromjpeg($_FILES['file']['tmp_name']); // Resize and write to temporary file $sizex = imagesx($file); $sizey = imagesy($file); if ($sizex > 600) { $newsizex = 600; $newsizey = 600*$sizey/$sizex; $img = imagecreatetruecolor($newsizex, $newsizey); imagecopyresampled($img, $file, 0, 0, 0, 0, $newsizex, $newsizey, $sizex, $sizey); imagejpeg($img, $PATH_TEMPIMG); } else imagejpeg($file, $PATH_TEMPIMG); // Store in mysql database $safeimg = "'".mysql_real_escape_string(getsafe(fread(fopen($PATH_TEMPIMG, "r"), $_FILES['file']['size'])))."'"; mysql_query("INSERT INTO test (image) VALUES (".$safeimg.")") or die(mysql_error()); ?> the problem is that imagejpeg() sometimes (not always!) corrupts the picture. It still shows, but presents weird artifacts and wrong colours. please note that it does not happen always: different compression ratios for different pictures may make it show correctly or not. the server has magic_quotes on (can't change that, I'm not serveradmin) but my function getsafe() should get rid of that problem. has anybody experienced something similar before? any suggestions? ---- Server IP: 213.92.11.19 Probable Submitter: 151.47.133.40 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.imagejpeg.php Edit -- http://master.php.net/note/edit/62935 Del: integrated -- http://master.php.net/note/delete/62935/integrated Del: useless -- http://master.php.net/note/delete/62935/useless Del: bad code -- http://master.php.net/note/delete/62935/bad+code Del: spam -- http://master.php.net/note/delete/62935/spam Del: non-english -- http://master.php.net/note/delete/62935/non-english Del: in docs -- http://master.php.net/note/delete/62935/in+docs Del: other reasons-- http://master.php.net/note/delete/62935 Reject -- http://master.php.net/note/reject/62935 Search -- http://master.php.net/manage/user-notes.php
