// version 1.2.0 - 22nd November, 2003
//
// Description
//
// This class will display a random product from your CafePress store.
// You can supply a simple template to control style, and have the
// output link directly to the shown product or simply to your main
// account. You can cache the results so you don't have to connect to
// the CafePress website all the time. Images can be cached and work
// on the same time length as the product list caching. Images can
// also be resized as desired before saved into the cache.
//
// This has only been tested with the free accounts from CafePress,
// and requires PHP 4.1.0+
//

// Example of use
//
// $cp = new cafePressBox('collingtons');
// $cp->setCacheDir('./cache');
// $cp->setCacheTime(86400);
// $cp->setCacheImages(true);
// $cp->displayItem(true);
//
// With a REALLY simple template
//
// $cp = new cafePressBox('amnuts');
// $cp->setTemplate('<div align="center">[IMG]<br>[TXT]</div>');
// $cp->displayItem(false);
//
// [IMG] is where the product image will be displayed
// [TXT] is where the product text will be displayed
//
// Example with using a category with a paid-for account
//
// $cp = new cafePressBox('amnuts', '123456');
// $cp->displayItem(true);
