I was having a similar (maybe the same?) issue with my Snippets view. The picture would show in the note, but not in the Snippet view. It happens inconsistently. To work around this, I opened the Windows Snipping Tool, snipped the picture in the note, then copy and pasted that snipped picture back into the note. Once I do that, the image displays in the Snippet view. I can't explain why this works, but you might try it.
