Another simple method to use is URI.parse, in your case would be

require 'uri'

(URI.parse(root_url) + image.url).to_s

and some examples:

1.9.2p320 :001 > require 'uri'
 => true 
1.9.2p320 :002 > a = "http://asdf.com/hello"
 => "http://asdf.com/hello" 
1.9.2p320 :003 > b = "/world/hello"
 => "/world/hello" 
1.9.2p320 :004 > c = "world"
 => "world" 
1.9.2p320 :005 > d = "http://asdf.com/ccc/bbb"
 => "http://asdf.com/ccc/bbb" 
1.9.2p320 :006 > e = "http://newurl.com"
 => "http://newurl.com" 
1.9.2p320 :007 > (URI.parse(a)+b).to_s
 => "http://asdf.com/world/hello" 
1.9.2p320 :008 > (URI.parse(a)+c).to_s
 => "http://asdf.com/world" 
1.9.2p320 :009 > (URI.parse(a)+d).to_s
 => "http://asdf.com/ccc/bbb" 
1.9.2p320 :010 > (URI.parse(a)+e).to_s
 => "http://newurl.com"
