Trouble aligning image

Yes, you can adjust that. There is a filter on the inline style added to the images in the feed. If you add this to your site, it should do what you want:

add_filter( 'send_images_rss_excerpt_image_style', 'prefix_change_send_images_margin', 10, 2 );
function prefix_change_send_images_margin( $style, $alignment ) {
	if ( 'left' === $alignment ) {
		$style = 'margin: 20px 20px 20px 0;';
	}
	return $style;
}

Please practice safe coding, make sure your site is backed up before you go tinkering, etc. etc. Hope this helps!
