Wow! Can't imagine finding such a great bird in my own yard. I'm not sure what type of "thread" you want to link to, but you can easily upload the actual photo if you have it. I haven't done it for awhile myself, but try this:
-Click on the "Upload attachment" tab that you see below.
-Select "Choose file"; try not to use over-sized files since they won't fit very well without making readers have to scroll around the image.
-Click "Add the file"
-Click "Place in line"
-Click "Preview" and you should now see your image!
Hope this works for you. -Kris
