This script displays the image passed as an arguament in proportion to its original size if it is larger than $max which is again passed an argument.
Here $file should be a complete path + file name suchas:
/usr/home/leapinglangoor/pics/lagoors.jpeg
$max is the maximum X or Y an image can have
| <?php
function show_thumbnail( $file, $max )
{
$size = getimagesize( $file );
if ( $size[0] <= $max && $size[1] <= $max )
{
$ret = '<img src="'.$file.'" '.$size[3].' border="0">';
}
else
{
$k = ( $size[0] >= $size[1] ) ? $size[0] / $max : $size[1] / $max;
$ret = '<a href="javascript:;" onClick="window.open(\'image.php?img=';
$ret .= $file.'\',\'\',\'width='.$size[0];
$ret .= ',height='.$size[1].'\')">';
$ret .= '<img src="'.$file.'" width="'.floor($size[0]/$k).'" height="'.floor($size[1]/$k).'" border="0" alt="View full-size image"></a>';
}
return $ret;
}
?> | |
Here is the code of 'image.php':
| <html>
<head>
<title>Image</title>
</head>
<body leftmargin="0" topmargin="0">
<?php
echo ( is_file($_GET['img'] ) ? '<a href="#" onClick="window.close();"><img src="'.$_GET['img'].'" border="0" alt="Close window"></a>' : 'Invalid image filename, or no filename entered. <a href="#" onClick="window.close();">Close window</a>.' );
