Can I easyly change standby screen (splash screen)?

Hello everyone,

I’m trying to change the static image that is displayed when no assets are in use. I found the ‘img’ directory in my home folder (home/${USER}/screenly/static/img) containing the file standby.png. I attempted to replace it with one of my own images, using the same name and placing it in the same directory. After rebooting the device, however, the default standby image is still being displayed.

How can I change this? I’m not very experienced with coding (Python, JavaScript, etc.), so I might be approaching this incorrectly.

Thank you for your help!
