Explanation? OK, See if this makes sense.
In the previous years gone by, I would use PB as the picture host. Then they went screwy for a while.
Then I tried using this sites, "insert image" icon, which also proved problematic. I thought there was a "paper-clip" icon, that allowed me to post pics from my own computer, but maybe I'm thinking of another site?
But now it appears PB has their act back together again, cause it looks OK....for now. Not sure what's changed from a couple months ago, when I had the problem, but don't feel bad. Me, computers, (and anything electronic), have never seen eye to eye. One of the many reasons I refuse to buy into these new "smart?" phones. That, and the fact the world will now suffer from advanced stages of osteoporosis. (And not even realize it)
