In general it’s recommended to always upload images with size of at least 1030 x 438px – and max size 2MB this will ensure that the site can generate all thumbnails:
- 1030 x 438px (Thumbnails for the MH Slider widget)
- 678 x 381px (Thumbnails for featured images on posts, archives and widgets)
- 678 x 509px (Thumbnails for some custom widgets)
- 326 x 245px (Thumbnails for archives and widgets)
- 80 x 60px (Thumbnails for some custom widgets)
If you have previously already uploaded images on your website or embedded images into your posts and pages, it may happen that these images don’t appear as expected or that your images are inconsistent in size.
