If it's necessary or makes sense. Also as long as you don't duplicate that image into more than 2-3 spots (3 is pushing it for me sometimes) but yeah. It can help for people that are just a specific fan of someone, so they might like one character but not the whole show so would still like all the image of this specific character

Thanks,any duplicates I've done has been a couple of wallpapers that were relevant to other spots and a couple of icons for the same reason so I guess it's not a big drama. Cheers.
