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??
