Woof.
Okay, restricting oneself solely to GD 1.x (gak) and PHP 4.1.2 does
change the ground rules quit a bit...
Honestly, your BEST bet is getting current GD and using one of the
pre-existing galleries.
That said, the two requirements you gave initially:
slide show
thumbnails
are both completely do-able in GD 1.x
SLIDE-SHOW:
<?php
//Change the next 2 lines for sure:
$path = "/full/path/to/your/photo/directory/here";
$url_path = "/just/from/homepage/to/your/photo/directory/here";
$dir = opendir($path) or die("Could not opendir $path");
if (!isset($_REQUEST['file'])){
readdir($dir); //skip dir commonly known as "."
readdir($dir); //skip the ".." also
$file = readdir($dir); //should be a real image
}
else{
while (readdir($dir) != $file){
//do nothing, just skipping merrily along to find the file
}
//Okay, that was the image they just saw. Show the NEXT one:
$file = readdir($dir);
if ($file === false){
//They have seen the whole show... Start over? What?
//You get to code this part yourself.
}
}
?>
<html>
<head>
<title><?php echo htmlentities($file);?></title>
<meta http-equiv="refresh" content="1;<?php echo
$_SERVER['PHP_SELF'], "?file=", htmlentities(urlencode($file))?>"
/>
</head>
<body bgcolor="#ffffff"><table width="100%" height="100%"><tr><td
align="center">
<img src="<?php echo "$url_path/$file"?>" /></body>
</td></tr></body>
</html>
For making thumbnail, see http://php.net/imagecopyresized
That was in GD 1.x
The cooler, better, much nicer-looking imagecopyresampled came in 2.x,
I think.
There's a BUNCH of notes and examples there for this bit, so I'm not
typing another one.
