codice:<?php function img2big($src,$alt=NULL) { // Constants define(IMAGE_BASE, 'http://0x010.isf.it'); define(MAX_WIDTH, 150); define(MAX_HEIGHT, 150); // Get image location $image_file = str_replace('..', '', $_SERVER['QUERY_STRING']); $image_path = IMAGE_BASE . "/$src"; // Load image $img = null; $ext = strtolower(end(explode('.', $image_path))); if ($ext == 'jpg' || $ext == 'jpeg') { $img = @imagecreatefromjpeg($image_path); } else if ($ext == 'png') { $img = @imagecreatefrompng($image_path); // Only if your version of GD includes GIF support } else if ($ext == 'gif') { $img = @imagecreatefrompng($image_path); } // If an image was successfully loaded, test the image for size if ($img) { // Get image size and scale ratio $width = imagesx($img); $height = imagesy($img); $scale = min(MAX_WIDTH/$width, MAX_HEIGHT/$height); // If the image is larger than the max shrink it if ($scale < 1) { $new_width = floor($scale*$width); $new_height = floor($scale*$height); // Create a new temporary image $tmp_img = imagecreatetruecolor($new_width, $new_height); // Copy and resize old image into new image imagecopyresized($tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height); imagedestroy($img); $img = $tmp_img; } } // Create error image if necessary if (!$img) { $img = imagecreate(MAX_WIDTH, MAX_HEIGHT); imagecolorallocate($img,0,0,0); $c = imagecolorallocate($img,70,70,70); imageline($img,0,0,MAX_WIDTH,MAX_HEIGHT,$c2); imageline($img,MAX_WIDTH,0,0,MAX_HEIGHT,$c2); } // Display the image header("Content-type: image/jpeg"); imagejpeg($img); //echo "<img src=\"$img\" alt=\"$alt\" />"; } ?>
sembra tutto ok, ma perchè mi da errore:
Warning: Cannot modify header information - headers already sent by (output started at /home/[io]/public_html/alexindex.php:2) in /home/[io]/public_html/funcs.php on line 62
??
Qualcuno mi aiuta??
