How do I remove my photos from iCloud?
If you don't want to install the iCloud utility, you can go to iCloud Web Page, choose Photos and select all the pics you want to download.
But you have to click on every photo to download the entire collection, I did't find any "Select All" option (even CMD + A does't work).
But anyway, you're lucky, we're talking about 'just' 296 photos ;)
