It worked, thanks for your help. I changed the code to this: if ($size > 1048576) { echo "<p class=\"error\">The image file size is larger than 1MB. Please reduce the size of the image and try again</p>"; $errors = true; } else if ($size < 1048576) { The file size was being checked in bytes, which was the mistake

Any help please, been trying to figure out what the problem is for a couple of days know. The code is below: <?php error_reporting(0); $error_msgs = array(); $errors = false; //define ("MAX_SIZE","400"); //$max_size = "400"; function getExtension($str) { $i = strrpos($str,"."); if (!$i) { return ""; } $l = strlen($str) - $i; $ext = substr($str,$i+1,$l); return $ext; } if($_SERVER["REQUEST_METHOD"] == "POST") { $image = $_FILES["file"]["name"]; $uploadedfile = $_FILES['file']['tmp_name']; if ($image) { $filename = stripslashes($_FILES['file']['name']); $extension = getExtension($filename); $extension = strtolower($extension); if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) { echo "<p class=\"error\">Unknown Image extension</p>"; $errors = true; } else { $size = filesize($_FILES['file']['name']); if ($size > 1024) { echo "<p class=\"error\">The image file size is larger than 1MB. Please reduce the size of the image and try again</p>"; $errors = true; } else { if($extension=="jpg" || $extension=="jpeg" ) { $uploadedfile = $_FILES['file']['tmp_name']; $src = imagecreatefromjpeg($uploadedfile); } else if ($extension=="png") { $uploadedfile = $_FILES['file']['tmp_name']; $src = imagecreatefrompng($uploadedfile); } else { $src = imagecreatefromgif($uploadedfile); } echo $scr; list($width,$height)=getimagesize($uploadedfile); $newwidth=800; $newheight=($height/$width)*$newwidth; $tmp=imagecreatetruecolor($newwidth,$newheight); $newwidth1=200; $newheight1=($height/$width)*$newwidth1; $tmp1=imagecreatetruecolor($newwidth1,$newheight1); $newwidth2=50; $newheight2=($height/$width)*$newwidth2; $tmp2=imagecreatetruecolor($newwidth2,$newheight2); imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height); imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height); imagecopyresampled($tmp2,$src,0,0,0,0,$newwidth2,$newheight2,$width,$height); $filename = "images/". $_FILES['file']['name']; $filename1 = "images/small_". $_FILES['file']['name']; $filename2 = "images/thumb_". $_FILES['file']['name']; imagejpeg($tmp,$filename,100); imagejpeg($tmp1,$filename1,100); imagejpeg($tmp2,$filename2,100); imagedestroy($src); imagedestroy($tmp); imagedestroy($tmp1); imagedestroy($tmp2); } } } } if (empty($_FILES['file']['name'])) { if (isset($_POST['Submit'])) { echo "<p class=\"error\">Please select an image!</p>"; $errors = true; } } //If no errors registred, print the success message if(isset($_POST['Submit']) && !$errors) { header("Location: success.php"); } ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xml:lang="en" xmlns="http://www.w3.org/1999/xhtml" lang="en"><head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type"> <meta content="en-us" http-equiv="Content-Language"> <title>Image Upload</title> <link href=".css" media="screen, projection" rel="stylesheet" type="text/css"> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script> <style type="text/css"> a:link { color: #00F; } a:visited { color: #00F; } .error { color:#F00; } </style> </head> <body> <form method="post" action="" enctype="multipart/form-data" name="form1"> <p>Picture</p> <input size="25" name="file" type="file" style="font-family:Verdana, Arial, Helvetica, sans-serif; font-size:10pt" class="box"/> <p>Image maximum size <b>400 </b>kb</span></p> <input type="submit" id="mybut" value=" Upload " name="Submit"/> </form> <p> </p> <p><a href="images/">Images Folder</a></p> </body> </html>
