You can edit and amend your post many times, at least until 12 hours after the moment you published your post. So no actual reposting is needed, you can just edit and fix the existing post - you should see the EDIT button just below your post.
I can see you already know how to add images, as you successfully did it for your earlier posts. So I have only this advice: for hosting images please use this website (you don't even need to sign up with them to use the service). If you upload images there, they are more likely to stay for good (other image hosting services are likely to remove your images after some time).
Regarding copy rights for images, I guess you can use anything you find on the Internet but just add the original source of the image.
For example:
which translates into this markdown:

As for formatting, you don't really need to use markdown any more - just switch to the editor mode (there is a button for this in the top right corner of your screen visible when you are composing a new post). Or just use the markdown as described here, the basic stuff (e.g. different types of paragraph headers) is very easy.
I appreciate it. It would let me post a picture but only at the bottom. Glitch in the matrix I guess. My wifi here is touch and go, Cambodia and all, unless I'm at my friends place and it's late here. I will see what I can do tomorrow. Thanks for the help and taking the time. I just felt eager to post it. Next time I'll spend more time on presentation for sure.
@innuendo "Regarding copy rights for images, I guess you can use anything you find on the Internet but just add the original source of the image." No, not true. I have many images on the internet and being credited is not satisfactory. Especially if someone is profiting off the illegal use of my work.
I get your point. So how can one know if being credited is satisfactory or not?
@innuendo, good question. I don't imagine any artists would be willing to give permission without getting a cut. Sadly it's being done all the time. Best bet is stock image sites - even those aren't free. If you are making money off of an image (directly or indirectly) that you have not paid for in some form - like a licensing agreement of sorts, you are risking a lawsuit. And you will 99.99999% lose.
No worries, when I start using pictures, I will use my own, or simply some from the public domain as I may if I re work this for better presentation, but I really do appreciate all the feedback and input. Thanks again @innuendo and fairytalelife...
