FYI,
I've had quite a few times lately where my pics, once viewable, only showed up as a box with an "X" in it. Last night I moved my pics from sharemation.com to photobucket.com, & all seems better now.
photobucket.com is free, & very user-friendly. And, I didn't need my teenager to show me how to work it. . .
For what it's worth,
Paul
