Recommended image sizes

• Full image is the default image you upload via media uploader.
  Recommended full image size is : 1170px X 585px

  Though smaller size images than recommended will not break anything, above image size will work gracefully for full width layout and home page featured posts slider.

• Theme do not recommend any specific different sizes for others like thumbnail, medium, large.

  Works fine with default WordPress image dimensions :

  thumbnail	150px x 150px
  medium	300px x 300px
  large	1024px x 1024px
