What is the easiest method for making an image plane half-transparent? I'm just setting up an image and I have to use units, so I want to see the grid when looking from top. Currently the image blocks the grid. Just want to make the image a little transparent. Must I use shader properties etc?? I'm new to blender sorry

And also 'Alpha blend' from the settings of that material:



And you may need to be in Material Preview or Display Render mode:
