Is it possible to create animations through Photoshop?

Yes Its possible as Alex Dalianis Say and I am more to say do it in internet with good website which offers you the bestquality.

Yes its possible but it would be better to design your animation firstly at Illustrator or corel and then transfer it at photoshop.

You can create a .GIF animation, not a complex video like what i believe you are suggesting.
