I am having a similar problem. I have a premium subscription. I have been cutting and pasting images into a note for a project I am sharing with others, and the images and written notes have disappeared twice. It's happened twice now in the last 24 hours. The first time it happened, the image that displayed in the side bar menu was actually not even in the note any more when I clicked on the note. I consciously saved the note during the process during the second time around, just to be sure it didn't happen again, and it DID happen again. This renders Evernote unusable for me. It takes me hours to build these "picture boards" for others to use for their projects. Any suggestions about 1) what is going on and (2) how to retrieve these missing pictures?
