Post Photos Not Coming up on Homepage for Blog Classic Style

I am a big fan of Tayp. It is elegant and very user friendly. I love it!

I switched from masonary grid to classic blog style with right hand sidebar. The text for my blog posts comes up but no photos. I double-checked and each post has a featured image and when you go to the post page, the featured image is at the top of each post.

When I switch to the ‘image’ format option on each post page, the photo on the homepage becomes enormous; twice the size of the Tayp demo and far too big for practical purposes.

What can I do to ensure:
1. The photos appear on the homepage in the list of posts and
2. Ensure they are the size in the Tayp demo

Thanks a lot,
