Photos dissapeared from notes

Hello everyone,

I had some photos stored in my notes and some of them do not appear anymore. When i try to open them it says the name of the jpeg and the size which as it says is 0 kb. i tried to open the notes from my computer through my web browser with no result. I should note that when i resized the photos to show them smaller they appear but when i click in one of them they don't open.

Thank you for your time in advance.
