All of the replies will work just fine for you. From this forum, I found out about the FastStone image viewer while trying to view RAW files (I too was new to the format). I believe it's at www.faststone.org I've used it for several months now, and it turns outto bethe only free program I've downloaded and then subsequently donated money to. Easy to set up, easy to use, good light editing and batch processing functions, and best of all, free. Just another option. gary
