Can't see how an image question could be off topic for -graphics. :)

Table won't necessarily help or hurt without more detail, but
consider:
A large GIF in 4 or 16 colors could be small enough. GIF compresses
using the -horizontal- dimension. Imagine two images (no pun
intended [G]), the same size, two colors. One has a lot of vertical
lines, lots of short segments of color when considered in the
horizontal dimension. The second has lots of horizontal lines. It has
fewer but larger segments in the horizontal dimension. The first
image will be much larger than the second.
JPG done with appropriate compression can be pretty small too. I've
seen very acceptable full screen (640x480) images that rolled in at
under 40k.
So, YMMV, depends on what 'kind' of image you need to put up and
exactly how you build it.
Have a :) day!
