Images
Use images when a screenshot, diagram, or visual reference belongs next to the note text.
Images are rendered directly inside your note from standard markdown image syntax. For local images, paste an image from the clipboard or drag an image file into the editor. massCode stores the file in the vault and inserts the markdown for you.
You can also use a remote image URL:
The masscode://notes-asset/ URL is resolved by massCode. Other Markdown apps may not display these local images directly.
Managed Storage
Starting with massCode 5.9, newly pasted or dropped images are saved to notes/.masscode/assets. When you copy or synchronize Notes between devices, include the whole vault, including the hidden notes/.masscode directory. Copying only Markdown files leaves their local images behind.
Compatibility
Vaults with images in the managed notes/.masscode/assets path require a massCode version that supports this layout. Older versions may not display these images.
Automatic migration
When a note references an image from the legacy notes/assets directory, massCode migrates that referenced file to managed storage and updates the note automatically. Unreferenced files are left in place.
