After much trial and error, upgrading and downgrading, I learned that the images are cached. So...if you change the size of the thumbnails, you must go into the minifp subfolder in your images folder and delete all of the resized images. Refresh your page and BOOM! The images are resized. It's terrible way to see your changes but it does work.

Now, what's with displaying the last image in the article? That's just terrible! Any work around for that? I would greatly appreciate it.
