2d animation import

Hi, can i make unity run sprites? i know that you can buy Sprite Manager but i am wondering if there is a code that makes the images play in a loop when the program runs and at the same time keep them in the same width and height

You could use this: http://forum.unity3d.com/threads/16763-SpriteManager-draw-lots-of-sprites-in-a-single-draw-call!

Or you can use this (I like this one): http://www.unifycommunity.com/wiki/index.php?title=Animating_Tiled_texture

And last but not least: http://www.unifycommunity.com/wiki/index.php?title=Animating_Tiled_texture_-_Extended

These are all pretty easy to use!
