I notice the code in the featured image markup which has &resize tagged on the end. When this is removed then the images look exactly like they are supposed to.
Do you mean you modified the add_image_size function found in the theme?
Where in the theme panel can I remove this unwanted addition?
Sorry, there is no option to change image sizes in the Theme.
You can modified the image size and use this plugin to regenerate your thumbnails.
