Remove the head bar showing the image path while hovering over image

[m3lab-zzl]

I understand the internal logics that when I edit a block, it will show the markdown source code, any other blocks will be rendered at the moment. This is at least reasonable. But I really hate it when I hover my mouse above any image, there is always a head bar telling me where the image is stored on my disk. I hate it because I do not want to know the image file path (by clicking the image I can edit the markdown source code and see the path then), and it always get me distracted.
