Blurry images

Hi, I looked for a thread about this but couldn’t find one.

My images turn out a bit blurry and I have no clue why. I used to have my feed displayed in the sidebar but since I moved it up above my header they aren’t as clear. I don’t know a ton about coding so the answer might be there.

Thanks!
