The web let's you do amazing thing with photos...

I love the way that so many free services are growing online to allow us to jazz up the boring things. If you have a bunch of photos from an office party or family shots or whatever it's now very easy to create some cool things like a slideshow or montage that can then be sent onto family, friends or even published on your blog or website. With these awesome tools even an amateur can create professional results.

What tools like this have you used and what have you created with them? I would love to hear from you.
