angelino Hi. Ok, I believe itwill do the same what my script did, but we can do it this way.

I do have a function which extract image from text:

function imageExtract( $text ) {
	$imagePath = '';
	if( preg_match( '/\<img.*src=.*?\>/', $text )):
		$imageStartPosition = JString::strpos( $text, 'src="' );
		if( $imageStartPosition):
			$imageEndPosition = JString::strpos( $text, '"', $imageStartPosition + 5 );
		endif;

		if( $imageStartPosition > 0 ):
			$imagePath = JString::substr( $text, ( $imageStartPosition + 5 ), ( $imageEndPosition - ( $imageStartPosition + 5 ) ) );
			print '';
		endif;
	endif;

	return $imagePath;
} // eof imafeExtract()

copy it above the changes advice and than replace the image value to:

<meta property="og:image" content="'.imageExtract( $this->item->fulltext ).'"/>
