Insert images as link from local storage

[LXj9atnQ]

In desktop app, when I insert images from local storage drawio slows down and gets laggy, also file size gets quite big.
On the other hand when the same images are inserted as urls from web, drawio works fine and file size are a lot smaller.
However there is no way (or I don't known how) to insert images from local storage which drawio will treat as link to file.
I would like to have drawio file and folder with images used in drawio (all offline, on my local storage).
This feature will help me and other people who worked with images inside drawio a lot.
Thanks.
