Today I spoke to one of your members: winch03200 and he gave me an idea.
Seeing the difficulty of people to create animated themes so I decided to create a small program (which will get better) is to quickly create file "raf" to integrate with your theme.
You need 7 files you can find in the SDK 3.41 from Sony:
You just select the images you want to use and choose how the theme:
=-Video Displays images quickly to simulate a video
=-Slide Show Displays images with a deteriorating
Then click on "create raf" to create the file "raf" that will be used to create your theme.
