To add a picture, you can simply use good old HTML code like this:
<img src="https://link.to.your.picture.jpg">

To quote someone, you can use Markdown like this:
> He Said, She Said

He said, She Said

or you can use the onsite editor or a wordpress editor if you want to write your article with image-links etc automatically, but it is good to know how an article is built up on Steemit, so have a go with it.

Welcome to Steemit :)

Thank you. My issue was with having to have my pictures hosted some place else apart from my PC or mobile but I guess I'll have to make do with what's available. Thanks for the tips.
