Theme Horse

Hi @dfreeman,

You can add the Google Ads on other sections through widget but sorry not in the Header Banner Section. For this you need to hire a developer to customize the code for you.

There is no any recommended sizes for the image on the slider. Any sizes are made to fit responsibly with the slider. But we recommend you to use the size of 1280 x 720. And please try to use the online image Compressor before updating the images on Sites. The compressor will help you to reduce to the maximum possible memory size of the image without affecting the quality of image. As we Recommend you to use https://compressor.io/ for compressing the image.

And yes our theme supports WP cache plugins.

Please Let us know if you have any other issue regarding the theme

Thanks
