pentax optio s4.

Anybody could tell me how can I put together diferent panoramic photos? Do I need some diferent software than ACD See for Pentax 5.0 or Foto Canvas 2.0?. Thanks a lot.

There are numerous programs to do this, google "photo merge" for a look.

I would throughly recommend Photoshop Elements 2.0 for all your image manipulation, and it has a nice merge function. It has all the features you can shake a stick at and for the price, few others come close.
