People love gif animation and always wonder that how to create their own animation. I am going to tell you about the simple and easy method in Photoshop. Just use the idea and understand it, you can create your own animations if you understand this idea. Here goes the demo of the image i created. i am using Photoshop 7 because i don't have Image Ready in my Photoshop CS 4 :)
Click here if below image animation isn't working.


Now lets start the tutorial, choose any image which you want to use as your project.

Now duplicate the image because we will change the duplicated image to use it in Animation. Double Click on the Layer to unlock it then right click on it and click on Duplicate Layer.

Now go to Filter > Liquify,i am going to do some changing on the the Duplicated Layer. Now use push tool and Drag the eyebrows to frown them.

Now we have two images now, one is simple and the other is with changed eyebrows. Now press Ctrl+Shift+M to open image ready or click on the image ready icon in the tools.

After opening the image ready go to Window > Animation to open Animation Window.

Now here goes the real thing, you have to pay attention here. Click on the eye of the layer shown in image with number 1 (the layer will be hidden now). Now click on the number 2 icon in the Animation Window, it will Duplicate the frame.

Now in step 2 you have to do the inverse of the step 1as shown in the image. Click on the Highlighted part (eye) of the layer to hide it.

Now go to File > Save optimized as
and save your image in gif file. Your animation is ready.
