And don't freak out if the quality is lacking. If you want to do frame animation, you need to use a lossless scheme. Jpeg is a lossy format, even uncompressed. So there could easily be artifacts that show up when you run the animation. And if they are compressed jpegs, expect them. Bmp, tiff, targa, png, are some of the more popular formats for frame animation, as they are lossless, and the latter 3 support the alpha channel. Or if you work in layers and your system can hack it, psd.
