I'm using the Forever Theme and am having trouble with the featured images for posts. Though I select medium size (200 x 300) for all the photos, some of the featured images appear as thumbnails while others are the medium size. Once you click on a post all the picture are the same size. I've used the same camera to shoot all of these pictures so I'm not sure what the discrepancy is. Does anyone know how I can avoid these thumbnail size images as the posts' featured images?
The blog I need help with is themckenziefamily.wordpress.com.
