I know, especially for beginner, Blender is overwhelming and seems to be to complicated to ever understand a thing...but if you keep on learning it you will soon learn how amazing Blender is and IT'S FREE!!!
So if you use this material setup:

you can choose the image in the image texture node.
Also set it to "clip".

After that you might see something like this:

which is of course not what you want.
So click on UV editing:

Hovering your cursor on the right window, press A to select all vertices:
![enter image description here](https://cdn.statically.io/img/i.sstatic.net/tZFbe.jpg)
now just use your mouse to rotate your view like this:
![enter image description here](https://cdn.statically.io/img/i.sstatic.net/JUBQ2.png)
then choose: UV -> project from view
![enter image description here](https://cdn.statically.io/img/i.sstatic.net/e62Xu.png)
if you now select "rendered view" you can already see parts of the image.
All you have to do now is adapt the UV coordinates on the left window like this:
Select A to select all UV coordinates, press S and scale and move your mouse so that the picture appears as you like it.
