Feature: When inserting an image, copy the image to the document path

[ProudRabbit]

Hi bro, this extension is really lightweight and user-friendly. Thank you for developing this extension.

But now I have encountered a problem where I use an absolute path when inserting images, which causes all images to be lost when sharing the document with others.

Could you add a feature to create a folder with the same name as the MD file in the path where the MD file is located when inserting an image, and copy the image to that folder.
