[Feature Request]: Simplify Image upload

[xstable]

Currently there isn't really any way to simply upload images. If you want to use an image in your note, you have to upload it first to your nextcloud-directory-structure, and you can only assign them to the note.

To make this note usefull, it's required to have an easy image upload like:

• paste from the clipper
• immediately upload from pc
• assign an still uploaded image (this is the only one that currently is available)
