The image I need is nested inside @summary, which Feedjira gives me.
Gotcha - that's different. The way the feed author did this, Feedjira can't help you much. The summary attribute is just a simple Ruby string. We can parse it with Nokogiri and get at the images - maybe something like this:
feed = Feedjira::Feed.fetch_and_parse("http://cltampa.com/tampa/Rss.xml?section=2065818")
entry_docs = feed.entries.map { |entry| Nokogiri::XML entry.summary }
img_srcs = entry_docs.map { |doc| doc.xpath('/img/@src').first.value }

Sweet, thank you so much. Last question, would it be possible to just retain all of the html formatting that the authors used?
Hmmm, not sure I get your meaning - could you provide an example of what's not working? The summary does have HTML in it, so I think you're good to use it.

Awesome thanks! How would I specific which image to grab? Each post that I am iterating through starts with an image, trying to display each one of those for each post.
