OK, here's the scoop.
Go pack to the main page of this forum and click on the FAQ about posting photos.
In Eric Gloo's reply, click on the "Photo Uploader." You will end up in a totally confusing universe, but don't despair, scroll down the screen and fill in the blanks. You will be able to search your own photo albums and insert any jpeg (only!) image.
Here is where it all gets messed up. You will be told that you have been a bad boy and must report to Frank's office. Ignore it.
In your own email inbox you will receive a new address where the photo is located at PW. Now it's a Copy/Paste sort of thing.
To insert a photo in a posting your must be in the "Full Reply Screen" and you use the fourth button from the left at the top of the answer window. Choose "insert a non-floating image" for reasons known only to those from other planets.
To gaze upon your brilliant photography, just preview your reply. At that point, if all worked as planned, you will start whooping an' hollerin'. Be careful not to cause The Jericho Effect.
Now, I must begin my novena in support of your quest.
