Hi @timelessriddle - Here is a great link to get some basics on Markdown http://assemble.io/docs/Cheatsheet-Markdown.html
I would also look into http://steemimg.com/ which was developed by @blueorgy It's a place where you can upload your images and then use the link for your Steemit blog pages. It's a great solution especially if you don't have your own website or FTP. Good luck and don't hesitate yelling out for help if you're still having trouble.
Extremely helpful information on images. Thank you!
