I've just come over from blogger and am struggling with putting images in my posts. I have resized the photos to what should be a good fit, uploaded them, selected the 100% and the full size options, and then inserted them into the post. In the editor the images appear correctly but when published are appearing as thumbnails.

In addition, I'm using the Triton Lite theme, which has a featured image option for posts. The images I select as the featured image are appearing distorted and blocky despite all my attempts to repair.
