Hello, jjnona!
Thank you for using Apple Support Communities! From your post, it sounds like you're looking for a way to edit iCloud photos from your PC. I love being able to edit my photos, and would be happy to lend a hand.
Since you wouldn't be able to edit photos directly on the iCloud app or on the iCloud website, you can download them, then use the editing software you like most to edit these photos.
Check out the section "Download your photos and videos from iCloud Photos" to download photos to your PC in the following support article:
Set up and use iCloud Photos on your Windows PC - Apple Support

Have a great day!
