In PHP, I do that. I use the PHP-imagick extension to manipulate the
images, and I have a script that will send either a nicely-sized
"fullsize" (often actually scaled down) or a thumbnail, based on a
parameter. When my CPU load gets high, I'll add a simple cache for the
thumbnail versions --
if(filemtime("cache/$filename") < filemtime("images/$filename")) {
make_thumbnail();
} else {
read_cached_file_and_send();
}
