PNG photo and www directory

Hello, I’m trying to use photo overlay to create a dynamic effect when my lights turn on using the “picture-elements” card. I’m running into issues—likely cache-related—with directory refreshing; whenever I change the photo (overwriting the old one) or switch directories, it’s as if Home Assistant doesn’t see the new directory or image at all. It’s frustrating to troubleshoot the paths because I’ve verified my redirects, yet even after restarting Home Assistant—or even the entire VM running on Proxmox—it still fails to locate the photos. Is there a specific step I need to take?
