From Halopedia, the Halo wiki
It's no worries lmao. I've already moved your images to proper filenames as its a patroller/ admin-only ability. More just something to keep in mind for future reference.
Hey there. When uploading images to the site, it'd be great if you can make sure to add a prefix to the filename of the image's source. For example, an image from Halo 3 would be "H3_ImageName.jpg" or one from Halo Wars 2 would be "HW2_ImageName.jpg". This makes the cleanup and tidy up around the wiki a lot easier.
