Just to add to what I needed to do to get the images to show. I would bring the post up on my iPad where I composed the post and on my iphone. I would then id the missing photos on my iPhone and then replace or insert the image again.
On another note, sometimes it takes several times to insert an image (my issue) and I will get the message that the image exists in my media folder. But then, I need to search through MANY images to find the image. Suggest that in a future upgrade you offer the user the ability to insert the image from the media folder WITHOUT the user needing to search for it.
Many thanks ROBERT
