It happens that you can easily accidentally double up on posting the same pic in a row. One correlation I've found in the forum gremlins making all my posted pictures un-viewable, is when I go back to try to edit a post with a picture in it. It doesn't always happen. But once I get a picture posted properly, I've learned it's risky to go back in Edit mode and try to delete a photo or add a written cation to a photo post after the fact. It can often lead to all the pictures of that batch turning to numbers that are un-linkable and un-viewable.
