Don't overwrite actor image

Would it be possible to implement a don't overwrite acctor images when you click download actor images when you manually add a actor image url so wehn you click Download actor images it wont overwite the orignal actor images that were first downloaded when you scrapedd theepisode. Since i tried scraping a tvseries from tvmaze first then the episode also from tvmaze and episode cast from imdb but, when i tried addding a actor image manually that was missing from imdb from tmdb since it was a movie the actor images were overwritten to mach what the url says the actor was from and it changed it to the imdb actors for that episode.
