How to upload and image to fusionpbx to change the logo (Rebranding)

I have been watching videos in the fusion membership portal on how to rebrand. The video does not get into how to upload the file. I have no experience in writing scripts for command lines. Everything I have learned up to this point has been through Youtube videos and trial and error. The videos are really straight forward and easy to follow. I've created a temporary document to upload my png logo file. I am using WinSCP to do the file transfer. For me this is an easier option to transfer the file. However, I am denied access to transfer file using FTP. How can I gain access to upload my logo? What commands do I need to use to allow me access to transfer the file over? I've uploaded the images to show you what I'm experiencing. I'm trying to move traill_Logo.png over to /var/www./fusionpbx/themes/default/images/

If anyone knows of an easier way. I would certainly appreciate it. I sent two pics to illustrate what I'm experiencing.

Thank you for getting back to me with a solution. Pardon me for my ignorance, but how would I login as a root user using winscp? I'm using AWS to host my system and there is a whole process they use for me to log in using a private key. It makes sense that I can do anything as an admin. Can you give me instructions on how to change my user status as root user?

Thank you... I was able to get it working over the weekend. Now when I log into WinSCP I can login as a root user which gives me the option to transfer files.

I use winscp all the time
however I login with root user to avoid such unnecessary issue
not recomending you should do it though... risky business
add your user to sudoers and i think you should be ok
