Yes, you can use such images.

We never recommend you to use dummy data if you have your own content. You can just import dummy data if you don’t have any idea about theme setup.
Let us know if you need any further help and instructions.
Thank you

For such case, you can just make the logo rotated and use it.

Do you want to rotate the image? Can you elaborate what design of logo you need? I just got confused about that.
