Easy posting ?

Hi, how can i easy post posts (try visit my blog and hover over “sund kost” i know it’s a different language but try then click “aftensmad” then you should see some pictures) like in the blog i have. so when i post a post the will be an option where i can insert a picture and then it will automatically make it round and set it to a site i can choose.

Thanks!

The blog I need help with is sundhedsliv.dk.
