This gem is on Gemcutter, simply type "gem install googlestaticmap" to install it.

Available on github at http://github.com/brentsowers1/googlestaticmap

Class for generating URLs for and downloading static maps from the Google Maps
Static API service.  GoogleStaticMap is the main class to use, instantiate it,
set the attributes to what you want, and call url on the instance to get the
URL to download the map from.  You can also call get_map to actually
download the map from Google, return the bytes, and optionally write the
image to a file.

== Examples:

Get a simple static map centered at Washington, DC, with the default size
(500 x 350), zoomed to level 11
  require 'googlestaticmap'
  map = GoogleStaticMap.new(:zoom => 11, :center => MapLocation.new(:address => "Washington, DC"))
  image = map.get_map

Get a map with blue markers at the White House and the Supreme Court, zoomed
the closest that the map can be with both markers visible, at the default
size.
  require 'googlestaticmap'
  map = GoogleStaticMap.new
  map.markers << MapMarker.new(:color => "blue", :location => MapLocation.new(:address => "1600 Pennsylvania Ave., Washington, DC"))
  map.markers << MapMarker.new(:color => "blue", :location => MapLocation.new(:address => "1 1st Street Northeast, Washington, DC"))
  image = map.get_map

Get a GIF satellite map, with a size of 640 x 480, with a
semi transparent green box drawn around a set of 4 coordinates, with the box
outline solid, centered at the middle of the box, written out to the file
map.gif:
  require 'googlestaticmap'
  map = GoogleStaticMap.new(:maptype => "satellite", :format => "gif", :width => 640, :height => 480)
  poly = MapPolygon.new(:color => "0x00FF00FF", :fillcolor => "0x00FF0060")
  poly.points << MapLocation.new(:latitude => 38.8, :longitude => -77.5)
  poly.points << MapLocation.new(:latitude => 38.8, :longitude => -76.9)
  poly.points << MapLocation.new(:latitude => 39.2, :longitude => -76.9)
  poly.points << MapLocation.new(:latitude => 39.2, :longitude => -77.5)
  poly.points << MapLocation.new(:latitude => 38.8, :longitude => -77.5)
  map.paths << poly
  map.get_map("map.gif")

=== Working from behind a proxy 
map = GoogleStaticMap.new(:proxy_address=>'my.proxy.host', :proxy_port=>8080, :width => 640, :height => 480)
