How do I delete photos from my iPhone 5C that are stored in the iCloud?

[iMore Question]

When I got my iPhone 5C, the person setting it up transferred my photos from my old phone (not iPhone) to the iPhone. Now, after a few months, the phone is telling me that my iCloud storage is too full to backup, and the only thing that seems to be eating up the space are these 76 (yes, only 76!) photos that were transferred. I have backed them up on my computer, and deleted all of my other photos from the phone, but I can't delete these. I was told to go to iCloud.com to delete them, but they do not show up there. The only place I can see them is on the phone, but, as I said, I can't do anything with them on the phone. I am trying to use icloud through Windows 7. I have tried looking through forums and helps and setting up photo sharing, etc, etc, but can't seem to find an answer anywhere. What is going on that I can't find/delete this pictures.
