I read a few articles about you wrote buddypress cover photo.
However, it is difficult because it is private marked.

How about organizing it for someone like me?

1. I want to use buddypress cover photo in crop format
like buddypress profile avatar.

2. I want to customize the buddypress cover photo upload image size
and use it as 800 x 600.

I’m not a developer,
but I don’t know the code at all,
so it would be better if you could attach some comments.

I am using a code snippet.
I’d appreciate it if you could organize it well and make a code.

I always support your business.
