Super cute dog!

Very cute dog, and a very cute wife too I might add!  The picture didn't show up in your post, I did have to cut and paste the URL into a new browser window to see it.

What a lovely photo! 

Finally! Success!
1. go to the Flickr photo you want to post  and click on that photo
2. then click on "all sizes" that appears above that photo
3. now, go to below the photo, where you'll see 2 boxes of "url/http" stuff....CLICK/COPY the SECOND BOX of jargon
4. to back to the forum and click on the envelope icon above the comment box (run your mouse over it - it says "insert/edit image"....
5. now just paste into the box that comes up and voila!  Your photo should appear!
I hate to admit that it took me all day to finally figure this out, but at least I feel a little bit smarter than I did a few hrs ago!...
