Copying and pasting without chrome extension

What I want:
When I copy and paste the image and text together on a web page, it is automatically converted to Markdown format and the image is saved locally. It’s like Joplin’s chrome extension.

Actual results:
But when I paste the buffer from the clipboard into the Joplin, the image disappears and only the text is shown.

In more detail:
I want to copy it directly from the web and paste it into the same file without using the extension. Implementing this using extensions keeps creating new files.

This can be done simply by copying one image from the web. What I’m saying is when a user copies images and text together.

I don’t think options like ‘Paste as HTML to Markdown’ will hurt Joplin’s simple design philosophy. Or wouldn’t it work as a silent function?
