A lot of old Lego sets have very small images in the Bricklink catalog. They
look like they were obtained from printed sources from the printed catalogs that
used to be included with those sets back in the 80s/90s. My suggestion is to
see if better quality and higher resolution images can be obtained from The Lego
Group for the Bricklink catalog. After all, Lego owns Bricklink. What does the
admin team think of this? Perhaps I am assuming too much and a convenient archive
of these images for all of these old sets does not readily exist for Bricklinks
use. It's worth checking into it. Are there any objections?
