I would say that you do not want to raytrace a picture and have the 
original result in JPG or GIF. 

Why ?

GIF: limited to 256 colours, and some americans would have a legal problem
  with a silly patent on compression.

JPG: the compression algorithm is with loss. Moreover the compression need
a spatial transformation of the picture, which imply you will only have the
file at the very end of the rendering (no Continue)

If you want a modern image format, go for PNG (and its already in POV).
It's lossless, 24 (or even 48 bits), can have alpha information like gif
and has no legal issue!
