Another solution would be to check if the file exists, before using getimagesize ; something like this would do : if (file_exists('not-existing.png') && ($data = getimagesize('not-existing.png')) ) { echo "OK"; } else { echo "NOT OK"; } If the file doesn't exist, getimagesize is not called -- which means no warning Still, this solution is not the one you should use for images that are

Warning: getimagesize(/Volumes/6134/jpeg/6134-1.jpg) [function.getimagesize]: failed to open stream: No such file or directory in /Library/WebServer/Dev/area51/scriptarama/results.php on line 57 I want to suppress just this error (not all warnings) because I know, through mismanagement, not all of our records in notice: getimagesize(): read the db will have an associated thumbnail. I wrote this function but it doesn't catch all of them: function getFileSize($logNum, $fileCount) { $fileSizeArray = array(); for ($i=1; $i<=$fileCount; $i++) { $path = "/Volumes/" . $logNum . "/jpeg/" . $logNum . "-" . $i . ".jpg"; if (file_exists($path)) { $fileSizeArray [] = list($width, $height, $type, $attr) = getimagesize("/Volumes/ARTARCHIVE/MerionPhotoArchive/" . $logNum .

If you don't have complete control of your hosting environment, you don't know what you can expect in the way of error handling if you don't do everything you can think of.One method I use in all of my programming is to place an '@' character in front of function calls that have potential for returning warnings or errors.@require($_SITE['ROOT'].$_FOLDERS['CONTROL'].'logger.php'); // suppress a file not found error @mysql_connect($host,$user,$pass); // suppress no connection error I recommend using the @ once your website is in production. I generally don't use the @ on development servers because I want to be aware of errors during development.
