Does anyone know what kind of tweaks I need to make to pertinent
configs to render an image correctly? Right now, the text of the
argument passed to imagejpeg is being shown instead of the image
itself.
Here's the code. This used to succeed until my hosting provider
changed something on his end. Now he's struggling to restore the
functionality that used to work.
<?php
// Resizer - decrease or increase an image's size proportionally
//
// Uses:
// creating uniform widths of heights for pages or tables
// Sample calls:
// <img src="resizer.ph p?imgfile=image .jpg&maxheight= 200"
border=0>
// <img src="resizer.ph p?imgfile=image .jpg&maxwidth=4 00"
border=0>
// <img src="resizer.ph p?imgfile=image .jpg&percent=0. 2"
border=0>
// Variables:
// $imgfile = name (and location, if needed) of image to resize
// $percent = in decimal format (e.g. enter 0.2 for 20%)
// $maxheight = in pixels, image's height will be set to value
passed
// $maxwidth = in pixels, image's width will be set to value
passed
//
header('Content-type: image/jpeg');
list($width, $height) = getimagesize($i mgfile);
if (isset($_GET['maxheight'])) {
$newheight = $maxheight;
$newwidth = $width * ($maxheight / $height);
} elseif (isset($_GET['maxwidth'])) {
$newwidth = $maxwidth;
$newheight = $height * ($maxwidth / $width);
} elseif (isset($_GET['percent'])) {
$newwidth = $width * $percent;
$newheight = $height * $percent;
}
$thumb = ImageCreateTrue Color($newwidth ,$newheight);
$source = imagecreatefrom jpeg($imgfile);
imagecopyresize d($thumb, $source, 0, 0, 0, 0, $newwidth,
$newheight, $width, $height);
imagejpeg($thum b);
?>
