Yes, Galileo observed the same areas as Voyager, and yes changes
between the two have been looked for, and none have been found.  You have
to remember though, of the four large moons of Jupiter, Europa was the
most poorly observed by Voyager.  Neither Voyager spacecraft got
particularly close to Europa.  So, in comparing Voyager images with
comparable Galileo images, if there was any change between the two, the change
would of been on a very large scale.  Galileo, of course, took images
much closer in to Europa and have more high-resolution images of
Europa surfaces, but the high-res images aren't too useful in finding changes
from the Voyager images because the Voyager images were taken at
lower resolutions.
