Export: images are exported as local links instead of embedded files

Hello!
While using Marknote for daily notes, I noticed an issue with export to PDF / HTML / ODT.
Images are exported as local links, for example: ![image](/home/zedqwe/whatever.jpg), instead of being embedded or copied into the export result.

It would be great to have embedded images during export or a checkbox like “Include images in export”.

Additionally, exporting the entire notebook at once, not only individual notes, would be very useful.

I use Marknote as a daily journal and would like to create yearly backups, including images, so that would be nice to have.

Thanks for the great app!
