Require help for pasting in picture from computer

Hi, my name is Guillermo, I work for awesomewebdesigns.ca and I love games, I'm new in this forum.

I need help with pasting a image to my mod description from the computer.
I only see link options for the images, but I directly want to paste it in, not to upload it on a web and have to put the link for it.

Anyway there?
