Hola a tod@s, tengo un Script que sirve para redimensionar las imágenes, pero tengo un problema, solo me funciona si las imágenes están en el mismo directorio que el archivo php que contiene el Script, o en directorios hijo, si por ejemplo quiero ponerlo de otra web no puedo... ¿ Alguien sabe como puedo hacerlo ?
A continucación os dejo el Script:
<?php
error_reporting (0);
header ("Content-type: image/jpeg");
/*
JPEG / PNG Image Resizer
Parameters (passed via URL):
img = path / url of jpeg or png image file
percent = if this is defined, image is resized by it's
value in percent (i.e. 50 to divide by 50 percent)
w = image width
h = image height
constrain = if this is parameter is passed and w and h are set
to a size value then the size of the resulting image
is constrained by whichever dimension is smaller
Requires the PHP GD Extension
Outputs the resulting image in JPEG Format

$img = $_GET['img'];
$percent = $_GET['percent'];
$constrain = $_GET['constrain'];
$w = $_GET['w'];
$h = $_GET['h'];
// get image size of img
$x = @getimagesize($img);
// image width
$sw = $x[0];
// image height
$sh = $x[1];
if ($percent > 0) {
// calculate resized height and width if percent is defined
$percent = $percent * 0.01;
$w = $sw * $percent;
$h = $sh * $percent;
} else {
if (isset ($w) AND !isset ($h)) {
// autocompute height if only width is set
$h = (100 / ($sw / $w)) * .01;
$h = @round ($sh * $h);
} elseif (isset ($h) AND !isset ($w)) {
// autocompute width if only height is set
$w = (100 / ($sh / $h)) * .01;
$w = @round ($sw * $w);
} elseif (isset ($h) AND isset ($w) AND isset ($constrain)) {
// get the smaller resulting image dimension if both height
// and width are set and $constrain is also set
$hx = (100 / ($sw / $w)) * .01;
$hx = @round ($sh * $hx);
$wx = (100 / ($sh / $h)) * .01;
$wx = @round ($sw * $wx);

$im = @ImageCreateFromGIF ($img) or // or GIF Image
$im = false; // If image is not JPEG, PNG, or GIF
if (!$im) {
// We get errors from PHP's ImageCreate functions...
// So let's echo back the contents of the actual image.
readfile ($img);
} else {
// Create the resized image destination
$thumb = @ImageCreateTrueColor ($w, $h);
// Copy from image source, resize it, and paste to image destination
@ImageCopyResampled ($thumb, $im, 0, 0, 0, 0, $w, $h, $sw, $sh);
// Output resized image
@ImageJPEG ($thumb);
}
