How to set up my start page

• the “upper picture”  seems like an image in a “slider”
• If you are using the “slick slider” plugin, here is the support link to request guidance: https://wordpress.org/support/plugin/wp-slick-slider-and-image-carousel/

• “lower picture” seems like it could be the “featured image” of a post.
• Here is the link for support for your theme to request guidance: https://wordpress.org/support/theme/ashe/

maybe the slider is included in the Ashe theme instead of a separate plugin.

Asking in the theme’s specific support area will be best. https://wordpress.org/support/theme/ashe/
