Nuts and Bolts
Incompetech is where I get all of my royalty free music for use in my videos. He has a huge selection of music of all different styles and lengths, so if you need some background music odds are he has a good piece for it. The songs I will mainly use in my videos are: Opening "Feeling Good", Closing "Honey Bee".
This the program I use to watermark my images. Easy and free. I found that if you set the watermark transparency to 100% that it also makes it easy to re-size entire batches of pictures.
