Another way to extract the URL and get only the path:

require 'uri'

tag = '<img src="http://www.ingolfwetrust.com/golf-central/aggbug.ashx?id=56f9e33a-6333-4daf-b4e1-137ddc051adf">'
File.basename(URI.split(URI.extract(b)[0])[5])
=> "aggbug.ashx"

Then you can check with File.extname to check for the extensions you
want, as others have shown.

Hope this gives you other ideas,

Jesus.
