A client side mod I created to project reference images and schematics into the minecraft world.

You need to be holding an ItemFrame in either your hand or your offhand to see the images.

Main Config Screen

The default key "O" will launch the config which will create folders for you to upload images in your filesystem:

{Minecraft}/config/blueprints/{world name}/{dimension name}

![Main config screen] Blueprint selection screen

The Reload button will rescan the filesystem for any files you have uploaded.
The 'Path' shows the relative position of the filesystem you'll need to work with outside of Minecraft
You can toggle the Render mode to hide behind blocks or always show through them.
Blueprints that are hidden show with a dark overlay.
You can use Control-Click as a shortcut to show/hide the blueprint in the world.
You can click on a blueprint to get to the moving and positioning screen.
In the bottom right, you can change the number of images per page to zoom in/out on the selection screen and navigate pages with the left and right chevrons.

Blueprint Moving and Positioning

Position and adjust each blueprint

Position tweaking is player-facing aware: e.g. left is always left
You can hold down Shift to increase the amount of change each button applies for bigger tweaks.
You can hold down Ctrl to reduce the amount of change each button applies for small tweaks.
You can hold down both Shift and Ctrl to make big changes to settings on each click.

A quick overview can be seen in this video which was the reason I created the mod:
