hi!
The most dynamic way would be to use a little php-progg which returns an
image like this (there are _many_ functions for image-manipulation:
<?php
header('Content-Type: iamge/jpeg');
$imgReal = ImageCreateFromJPEG($_GET['pic']);
$x = ImagesX($imgReal);
$y = ImagesY($imgReal);
// use a percentage to make the pic smaller
if(isset($_GET['percent']))
{
$percent = (empty($_GET['percent'])) ? 15 : $_GET['percent'];
$n_x = $percent/100 * $x;
$n_y = $percent/100 * $y;
}
// use a maximum width (height is proportional)
else
{
$maxWidth = (!isset($_GET['maxwidth'])||empty($_GET['maxwidth'])) ?
100 : $_GET['maxwidth'];
$newX = $maxWidth;
$newY = $newX * $y / $x;
}
$img = ImageCreateTrueColor($newX, $newY);
ImageCopyResampled($img, $imgReal, 0, 0, 0, 0, $newX, $newY, $x, $y);
ImageJPEG($img);
?>
You have to access this script this way:
<img src="ihavethecodeabove.php?pic=/path/to/file.jpg">
you have to remember that this script is called seperately by the browser so
the path to the pics must be ok for this script! Remember that this requires
enormous performance which _may_ cause long waiting times...
hope this helps?
