I've been struggling for some time to produce JPEG images from Pages to send out to friends and clients. Now this simple method gives me a quick and easy way to send out Pages documents - cards, invites, flyers or proofs - all straight from iPhoto. If you have a blog or a web-site these JPEGs are ready for uploading.
