Downloading my logo

Here is the documentation of themezee about they way you should insert the logo into their themes. I hope that helps. https://themezee.com/upload-your-individual-wordpress-logo/

Thank for your share

I used the link from Jeremy, and deleted then reloaded my logo from the media file. I still only get the little box on the upper left with a red x. I tried to use photobucket and do the same, with the same results. What does the red x mean?
