Seems like you have a good outlook on life. Sounds to me like you've had a very exciting one so far.
About the image, yes I do think adding an image to your posts will help you attract a crowd. Some people have written about this or have tested it and generally, the posts with images get noticed more.
The way I do this with all-text posts is to just add a header image.
Thanks very much !
If you want to do some formatting like add headers or use bold/italic, you should check out this post for some pointers.
The headers part doesn't work for me though, For this, I just use the <h1 to 6> tags.
Thanks. I was wondering about that.
