Maybe something like this:

array = colors.map do |color|
   ["http://www.mysite.com/file1/#{petpet}_#{color}.gif",
   "http://www.mysite.com/file2/#{petpet}_#{color}.gif"]
end
array.flatten!

or
array = colors.inject(Array.new) do |ar, color|
   ar << "http://www.mysite.com/file1/#{petpet}_#{color}.gif"
   ar << "http://www.mysite.com/file2/#{petpet}_#{color}.gif"
end
