Theme Horse

Thank you. Is this in the WWW>wp-contect>themes>clean-retina-pro-2>images ? Or public_html>wp-contect>themes>clean-retina-pro-2>images ?
I ask because I have edited the CSS and changed the image it pulls and nothing changed. Also I have tried deleting the image off the FTP site and it never disappeared from the site. I am a developer so I don’t have to hire one, I just need to understand where this is pulling from.

Also, I tried showing my client how to add media and it is giving him an error. Are there permissions I need to set up for other computer to be able to load media?

Thank you for your help!
