For a specific (but very useful) category of images, they're very
useful, basically because they can be far smaller as long as you don't
mind a few artefacts. It's not at all hard to make up very effective
thumbnails in a couple of K. Since bandwidth will always lag behind
storage, I think this is quite significant for the 'Web.
The code for handling JPEG is freely available for a variety of
platforms so it shouldn't be that hard to build in with the GIF and
xbm code.
Besides, if we've got inline JPEGs, we're about 10% of the way to
inline MPEG :-)
Just my two penn'oth
