Adobe Tutorial

To give an example of animated gif, i have tried an example of an animation between a cloudy day and a sunny day. You can create anything while you try this out :

1. Take any background as shown in the image :


2. Draw  a boatsman like as shown below in a new layer or same layer :

3. Now draw some clouds in a new layer a shown below:

 4. Now draw a sun in a separate layer a shown below. If you hide the clouds layer created in step above, you would see the following :

5. Now merge the layer background and the boatsman by right clicking them and create a duplicate of merged copy. Now merge one of these duplicates with layer Sun and the other duplicate with layer clouds such that you have your layers palette as shown below :
6. Now go to File menu>Save for Web and select the format as Gif, check the checkbox "animate". Check the "loop" checkbox and specify the delay timing. I have mentioned the delay time as 1 second. So this means, my two layers shown above will appear alternatively after a delay of 1 second.

7. Click Ok and you can check out your animated gif playing in IE or Windows Fax Viewer.
