Just in case this is of help to anyone who is interested, here is what I did to get the photos of my dogs on the Forum:
1. I went to Photobucket
http://photobucket.com/, which is free, and signed up with a username and password. No particular reason for Photobucket, it was the only one I knew about.
2. After I logged in, I opened up and named an album. Then, I went to "upload now", and uploaded photos of my dogs from my computer. Once this was done, I selected one of the photos from my album, and then went to "share" below the photo, one of the choices.
3. Then I went to "get link code".
4. I selected "IMG for bulletin boards & forums", and selected "full size".
5. I saved the link inside this box.
6. Then, I copied this link inside this box to the Forum site where I was posting, which, in this case, was "The Peregrine Room", "photos of members pets".
7. I pasted the link, then went to "preview" to see if it was there, and it was.
8. I wrote my message, and sent it off along with the photo in "post".
If anyone wants to give it a try, great; I hope I did not forget any steps.
