Insert pictures in Minecraft?

As you can see from the title I'm looking for a way to insert images in Minecraft, in the latest version. In old versions, I know how it works, but in the latest I have not found a single way. Can anyone help me further?

The method I know is that you change the image of an "image" item in the data files and create a texture-pack, so to speak

It goes with a Spigot (Minecraft server software) plugin called ImageMaps. That should work.

There's another possibility kit, with ImageToMaps. This will create on the PC maps of normal images, which can be by command ingame. Only for owners, not for players.

The chat command would be: / minecraft: give ga minecraft: filled_map {map: 30002} 1

map: 30002 would then be created by you map.
