It's just old; back in the day HTML had very little graphic capabilities, and loading multiple images was comparatively slow (think 56k connections). So you'd load a single image and then subdivide that in clickable areas with image maps (which is what this is called).

Isn’t it an image map? No one uses them any more I don’t think but they had their time.

As other commenters have said, this used to be a very common technique.

I was reading an essay on Paul Graham's blog[1] and the side panel[2] seemed erringly pixelated even on my MBP. I inspected the web page and found that the whole side panel is infact a gif[3] and the different links on the page are linked using the coordinates of the image.
Example for the first link: <area shape="rect" coords="0,0,67,21" href="index.html">
TBH, I did not know this is something which can be done in HTML but that got me curious on how it ended up on PG's blog given many limitations it has :)
