Online Image Morphing

[millisami]

I have visited one of the Photo Slide Show servicing site rockyou.com
There one can upload photos and customize the animation of the slideshows via Flash.
But what I'm thinking of is to give the ability to morphing 1 image to another image and on.... online.
I did search but only found the softwares that do morphing on desktop and finally put that to web but couldn't find any service similar online.
Is this possible to do online using PHP??
