Default Why the eff is Drive syncing thumbnails in my wallpaper gallery? Pic.

So I went to change my wallpaper on my G Pad 8.3 and I noticed that there were a bunch of thumbnails in my gallery. Now, I recently downloaded unicon and Flatee icon pack on my N4. I believe the offending thumbnails come from that app. These are the only images that are syncing from drive. I have looked through the drive app and looked through my N4 to find where these originated so I can delete them, but can't find them anywhere. Someone please helo me out as I now have 100 images syncing across my devices and want to remove them. Thanks

Edit: It's not actually the app I thought it was. Drive shows the date as a couple of weeks ago....before I downloaded the app. However, those are thumbnails for an icon pack, no? Flatee was the first one ive ever downloaded and that was today. Unless drive is showing the date that the developer synced the images to drive? Any help appreciated!
