SimplePie is an open source RSS parser. Evidently, SimplePie can cache images from RSS feeds it processes. But I don't know what to make of the documentation.
The example code looks like this
$feed = new SimplePie();
$feed->set_feed_url('http://simplepie.org/blog/feed/');
$feed->set_image_handler('handler_image.php', 'image'); // handler_image.php?image=67d5fa9a87bad230fb03ea68b9f71090
$feed->init();
$feed->handle_content_type();
echo $feed->get_title();
But handler_image is not a file included with simple. However, after downloading various hacks and add-ons over time, I ended up with a file called handler_image.php. This is literally all the code included in the file -->
require_once('autoloader.php');
SimplePie_Misc::display_cached_file($_GET['i'], '../cache', 'spi');
It doesn't do anything.
I tried substituting handler_image.php with timthumb.php (which I have installed on my server) but that doesn't work either.
Any suggestions?
