One of my favorite starting pages is MET Museum catalog. Almost everytime I see a delightful artwork that I want to share with my twitter followers. That's the main use of this script.
This simple PHP script, scraps the information from a catalog page and downloads the main image, composes a tweet and sends it.
Each artwork has an unique catalog ID you can get fromt its URL:
http://www.metmuseum.org/art/collection/search/283277
// Catalog ID is 283277
// Test mode, show info in term, does not post tweet
// Useful for debugging
php -f MET-2-tweet.php XXXXX
// Add --send to post tweet
php -f MET-2-tweet.php XXXXX --send
