You have asked this question before; this might make some here concerned  
you  
won’t use the answers already provided.

Your best bet has always been Hpricot, to _find_, _store_, and  
optionally  
_erase_ the image sources. You already posted a solution with  
.search(’//img’).  
The step to _store_ the images would be something like this:

doc.search("//img").each do |img|  
puts img.attributes[‘src’]  
end

A further regexp using /.jpg$/ would match strings with .jpg on the end,  
but be  
warned there are many variations of image filenames, including, for  
example, .JPEG.

Please post back what you did with this advice (if anything!), instead  
of  
continuing to ask the same question over and over again!
