Steps to reproduce the issue

Not really a bug, but a common problem.

Displaying RSS feeds using com_newsfeed, many providers mistakenly use relative addressing to display images.

Expected result

A feed display which includes imagery.

Actual result

A feed display which includes numerous broken image links.

System information (as much as possible)

I built a simple fix for Joomla 3.x

Additional comments

It's an easy fix. Add the following lines immediately before line 126 (the echo statement which prints the $text variable):

$domain = preg_replace( "~^(https?://[^/]).$~", "\1/", $this->rssDoc[ $i ]->uri );
$text = str_replace( ' src="/', ' src="' . $domain, $text );

I'm currently supplying sites with an override html template which works fine, but I would prefer if this minor cleanup was included in the default Joomla Install.
