First, if it's possible (if the images will never be changed), your images
should be all contained within one image file, regardeless of what format
you use. If the format you use has image compressionand isn't truecolor, you
can save quite a bit of space by doing that alone.. as there won't be a need
for a color table for each image. Also, any colors that are duplicated  in
different images, won't need a new color table reference.
As with any compression scheme, the largergreater the amount of data to
compress, the greater the compression ratio.

Second, jpegs take relatively long to load.. if the images are small, and
image quality isn't very significant, I'd suggest GIF format. The
compression will be just as good if not better than JPG, and load times are
at least 3 times as fast.
The GIF quality isn't great, but it's not very noticable in small images.

You can also reduce the size of the images, if you convert them to 8bit
images, if they aren't already.
