Getting Started with Dreamwidth

Okay, so I've gone over the FAQs relating to posting pictures, and I cannot figure out how to do it. I've tried using my Instagram account to no avail. I've googled 'how to import pictures on dreamwidth' and couldn't find a satisfactory answer.

So please, if you can, can you show me or list the steps (one by one) on how you post a picture on Dreamwidth?
