Thank you for the tips. This is what I ended up doing, as a tip for anyone else that has this same question:
I went to my Flickr photo's page and clicked on the "All Sizes" option. At the bottom of the photo there is a box with html code, labeled "1. Copy and paste this HTML into your webpage."
Flickr's All Sizes option gave me this code to begin with:
<img src="http://farm3.static.flickr.com/2576/3954762286_9a22a62bc7_o.jpg" width="480" height="640" alt="Knudsen Farm" />
In a new post I went to the Add Image tool, and added my photo in the URL tab. I used the photo src location ("http://farm3.static.flickr.com/2576/3954762286_9a22a62bc7_o.jpg") and had the photo link back to the photo page ("http://www.flickr.com/photos/24831034@N08/3954762286/") that Flickr provides. I put in the alignment in the URL tab and "Added the Image to my Post."
This resulted in html with a caption, alignment info, and a link back to my Flickr photo page. I went back to the Visual view of my new post and clicked and dragged the photo to a manageable size, and repeated with a second photo until they both fit.
Not as automatic as I was hoping for, but it will work.
Thank you for your help,
