Hi there,
1. You can template override the following file to remove the post cover: JoomlaFolder/components/com_easysocial/themes/wireframe/helpers/user/mini.header.php
For the rest, you can simply use custom css to change the css rules(http://take.ms/kuxvV).

2. I don't really understand what you mean here. There is a share button in the stream item in ES page(http://take.ms/m1JX3). If you are referring to something else, can you elaborate more or provide some screenshots if needed?

In the Joomla article, how can we share this article in Easysocial, in the same way that we can share this article on Facebook, Twitter or Google+.

Note: in the stream item in ES, a "share" button and a "social share" button exist. It takes a similar button in the article page.

How do I get the "share" button on the Joomla article?

To sum up, it's about being able to share a Joomla (or Easyblog) article on Easysocial.

The sharing of Joomla articles towards Easysocial is an essential function.

Best regards

Hey there,
We do not a social share button that shares posts to EasySocial. However, you can check out this plugin which may help you with it. But before you make any purchase, you should contact the plugin provider first to make sure it works with the latest version of ES.

It's too bad. I find it curious that a social application does not have the most obvious thing that is to have a social sharing button.
I hope you will come forward with that one day.

Thank you for your advice.

Very sincere greetings
