I'm new to Facebook. I was asked to design and create a business page for the customer. He has a business FB account.
I've tried to create a page, upload an image on it (although it was cut to 851px x 315px). Seems like that's not what I'm actually need. So, I'm stuck. I've read Why can I not create an application on my Facebook page? , but I'm still curious if I really need to choose an App on Facebook from https://developers.facebook.com/apps application or I have to do it in another way.
I want my image on FB to be about 800px to 800px and have some text, my own buttons above the image that link to the business page etc.
I think I need something like this company has on FB (just an example). But, I don't know from what link at Facebook I should start?
