Add new ads size

Hello,

You can use the element Ad Box, and set the element where you want.
The ad box has 3 sections for ads: using theme panel ads -> https://i.imgur.com/KFa9ibl.png, using images/banners -> https://i.imgur.com/MfAPTaE.png and custom code -> https://i.imgur.com/2rh8SuD.png save it and will appear on the post (you can set a shortcode like a shortcode from adrotate plugin or other plugins)
You can set the image width and height -> https://i.imgur.com/g0h23Q8.png

Thank you!
