Your images are not showing up.
The format is:
The images have to be stored on a server, up on the web. Steemit has a place for that https://steemimg.com. You must sign up for an account and and give correct email address. Click the email verification once it finally arrives.

Once you upload a photo there will be a box with a link. This does not cause your photo to show. Click the down arrow in the upper right of the box.

Choose the 'Markdown Full' option. Select all of it then copy. Click edit on your post and insert the new code. Your picture will show immediately in the preview window below.

You can also have the images somewhere else like flicker for yahoo, one drive for google and so on
