Photos not displaying correct size and aspect ratio

NOTE: I copied the "page source" on an old website page I am mirroring and posted it onto my page for easy access while recreating the text and inserting the photos. Then I deleted the old page source from the page. I'm not sure if this might be related.

I'm having this problem with a bunch of photos on the page I am editing: https://www.darkshadowsplay.com/JFcom/Biography/

1. The first screen cap below shows the normal size of the photo while viewing it in Paintshop Pro.
   

2. The second cap shows how tiny it is when I use the "Single Photo" widget to display it on my page. At first it was tiny and square. Now it is tiny and with the correct aspect ratio, but really small (I don't know why that changed). The only way for it to not be small is to choose 'Photos size: Fill Width," which makes it huge, and obviously distorted enough that it is being resized from the tiny size. All other options, small, large, fit width, the photo is tiny.
   

3. The third cap shows that it is distorted when I view the gallery in organizer.
   

4. The fourth cap shows that the photo is the correct size when I view it in SM Editor.
   

Thanks for your time.
