These are the instructions for uploading images into your WordPress.com blog. You can also upload images directly into your Media Library using Media -> Add New.. What do you mean by import please? Do you have content from another blogging platform in an XML export file that you want to import?
I have the images in my media library. I’m curious what the most pleasing way would be to display before and after pictures. Also, is there any way to put a border around the pictures or anything like that?
