Gallery Captions and RSS

I use WP 3.5.1 and the latest version of Suffusion theme. I created a gallery for a specific post with captions for each image using the create gallery option on the add media page from the post edit page. It displays as expected on the blog at http://www.ramblingbarba.com/photo-friday-28/

However, the captions do not display at all on the various readers I have checked. I notice in my feed (sample below)the caption is included in the feed with the “alt=” attribute and not the “caption=” attribute.

<a href='http://www.ramblingbarba.com/photo-friday-28/kickflip/' title=''><img width="300" height="300" src="http://www.ramblingbarba.com/wp-content/uploads/2013/05/kickflip-300x300.jpg" class="attachment-medium" alt="We went to the park this week on a recognizance mission. I shared earlier...guys were really good skaters." /></a>
I used the shortcode [gallery size=medium] for this.

Captions on individual images in other posts show up just fine. Here is a clip from the feed for a recent post http://www.ramblingbarba.com/jesus-street-cred/ :

<div id="attachment_3553" class="wp-caption alignleft" style="width: 399px"><img class="size-full wp-image-3553" alt="Street Cred" src="http://www.ramblingbarba.com/wp-content/uploads/2013/05/bullseye.jpg" width="389" height="434" /><p class="wp-caption-text">Street Cred</p></div>

I added a caption for the purpose of trying to figure this out. This is an individual image and not a gallery. The class=”wp-caption-text”>< is included therefore the caption is included in the feed and is displayed with the image in readers. This isn’t present with the gallery function so even though the caption is present in the feed it isn’t being displayed with the image.

Is the only way to have a post of images with captions to individually load images and captions without using the gallery option to get the mark up needed for the captions to display?

Thank you for any help
