I previously discussed a command-line tool for generating image tiles. I've updated the tool to include an additional parameter for image format. Usage is as follows, and the tool is available for download:

C:\tilegen /?
Generates a directory of tiles from a source image equirectangular projection

TILEGEN [drive:][path]filename level [/S=size] [/D=directory] [/F=filename] [/I=image]

   [drive:][path]filename   Soure image
   level                    Level of detail (0-based)
   /S=size                  Size of tile, default 256px
   /D=directory             Directory format, default level{0}
   /F=filename              Filename format, default {col}_{row}
   /I=image                 Image format (JPEG, PNG, TIFF), default JPEG (Compression=90)

Note that the source image is not scaled so must be correct level and size,
i.e. width (px) = 2 * 2^level * size, height (px) = 2^level * size
