Instead of using a regular expression you could consider a html parser ,
and/or do a xpath search to retrieve images. Check hpricot .

Yeah, it is quite easy with Hpricot:

require 'open-uri'
require 'hpricot'

site = Hpricot(open("http://code.google.com/edu/submissions/SedgewickWayne/index.html"))
site.search("//img") #=> returns an array of all images

yes i used as this
doc = Hpricot.parse(item.description)
imgs = doc.search("//img")
@src_array = imgs.collect{|img|img.attributes["src"]}

but it gives only the Image Url's but I need to Get
<img src =" "> tag Fully ...

Then do

@src_array = imgs.collect{|img| "<img src =\"#{img.attributes["src"]
}\">" }
