Probably the two most used formats are PNG and JPEG. PNG is good for
images with few distinct colors - typically, rendered vector data fits this
profile well. To really optimize the bandwidth usage in PNG output, you
can use a color palette[1].
If there are not a lot of areas of constant color (for example, serving
imagery,) JPEG is probably a better option.
For the case of symbolizing point graphics, PNG is probably the best option.
