Materials are not working for me

When I make a material I want to add the image but there are no options for me to do such things. I have tried all of the shaders and no options pop up for me to add a base. What is happening within my unity program? Are there settings I need to change?

You may have accidentally minimised the material component in the inspector. Click it once to see if it expands.

In the inspector: click on the name of the material. This works as a dropdown for the material hiding/showing the material settings.
