Drupal 7 Feeds to grab images inside tags

I have a feed link with in the following format

<item>
<title>Lorum ipsum</title>
<teaser>Lorum ipsum</teaser>
<description>Lorum ipsum</description>
<link>http://www.example.com/article/?ad=1</link>
<image>http://www.example.com/image/123456/248x500?.cached</image>
<author>noreply@example.com</author>
<pubDate>Wed, 2 May 2012 14:22:24 +0200</pubDate>
<guid isPermaLink="false">http://www.example.comARTICLE12345678</guid>
</item>

I am trying to grab the images inside the tags to a separate field in Drupal, but so far nothing is working. Tried many tutorials but except image everything is saved.

What can be the solution? Many thanks
