Image questions

Thanks. Yes, I believe I am referring to the type of blog pictured above. However, it’s not functioning the way I anticipated. Perhaps I’m doing something wrong or my expectations are incorrect.

I was expecting the theme to use one image size on the blog pages (a thumbnail) and a different image size on the post pages. I am performing the following steps: 1) uploading an image to the wordpress media library. The size of this image is 710×360 (which i believe is the max size allowed by the theme for a post image). 2) Setting a thumbnail for the image within the wordpress media library with a square size as described above. 3) Adding the image as the blog post’s featured image.

With these steps, I was expecting the theme to call on the large image for the post image and call on the “thumbnail image (smaller square image) for the blog page. This is not happening. Instead, the theme is using the large image and cropping the image to a square resulting in awkward unusable images.

Are my expectations incorrect? If so, is there a way to make the theme use the large image for the post page and the thumbnail for the small image on the blog pages?

Thanks
