Expound theme and post images

I added a post to my blog last night and for some reason the images haven’t attached to the post. I went through the usual process and it all looked as normal but I can’t get a post to attach the top of the post or a feature image.

Can anyone offer any suggestions please?

Also the layout has altered:

I did have the main post at the top as a featured post with the horizontal block of four or so posts underneath. Now I have the featured post at the top and the others in a vertical list below.

Before this happened I did add an image widget to the sidebar – I have deleted that to see if it makes a difference but it hasn’t.

Cheers for your help.
