Adding custom themes

[Efficient_Good_5784]

While I have you, what's the easiest way to add text to the cover of Movies on the homepage? My TV Shows says "TV Shows", my anime says "Anime", but movies appears to be just a random image from one of my movies. I see where I can edit the actual image, but how can I get it to say "Movies" on it, so it looks more uniform? 

Also, it seems like years ago, when I was playing around with KODI and PLEX, there were resources to download cool images to use, instead of just a random image. Any suggestion on that? What can I search for that will bring up something that will fit nicely there?

Photoshop would be your friend here. Just edit the image to have the text over it and upload it as the library's image.
The way it works right now is if you don't add a personal image, a random image will be picked periodically and the library's name pasted over it.
If you add a custom image, it will be the image without the name over it.
