Welcome PoconoChris!
Sounds like a fun project!
There are three ways that I know of to post an image.
There are buttons above the window where you type. The top row is mostly to modify the letters, i.e. Bold, Underline, etc. The second row has the buttons for inserting items including pictures.
The first two buttons on the second row are for using another place that has your images.
1st is "Upload" and it opens MyWillysPics.com. You'll need to make an account. I haven't used this much yet.
The 2nd button is "Insert Image" for posting an image, from Flickr, MyWillysPics or some other platform that allows you to store pictures. Copy the images URL and add it in between the image commands you'll see after pushing the 2nd button.
The 3rd way is just below the window you're typing there is a "+ Attachments and other options" click that and you can load images, documents etc. directly from your computer to the bottom of your post. When you preview, you won't be able to see those attachments. You'll have to post and then see them.
I suggest checking your image size to ensure it will display easily. Most of my images need to be reduced where it will display easily on a screen.
Practice it until you find a way you like.
