Derive your appliation container class from MPAlbAnimationObserver, and declare these

CPAlbImageViewerBasic* iViewer ;
    void Notify( TAnimationEvent aEvent );

And, in your container,Animation method/function use this code. Dont forget to return count in CountComponentControls() and iViewer pointer in ComponetControl() methods.

iViewer=CPAlbImageViewerBasic::NewL(this,aRect);
	iViewer->SetAnimationObserver(this,ETrue);//for looping 
	iViewer->LoadImageL(_L("c://nokia//images//anim.gif"),EColor4K);					
	iViewer->PlayAnimationL(); // support image and animation
