On the theme (Origami), when I insert a blog image...the image takes the width of the blog area and the text is under the image That is perfect. (see attached Origami1.png)

However, in the Elegant White theme....the blog image is sized to 1/2 the width of the blog area and the text is side by side with it. (see attached White.png)

I want to use the Elegant White version...but would like the image to be sized like the Origami with the text underneath. How can I do this?
