I have been playing around more yesterday and today with creating more collections. However, I am sometimes finding it difficult to find already created 16:9 images to use for them. Some of the more popular collections are pretty easy to find on Fanart, TMDB or TVDB but it's not easy with some lesser known movies that I put into collections. It seems really easy to find poster images for collections but not 16:9.
I was curious what others may use or how you get your images or if you create your own. I have made a few of my own with some downloaded textless images and used those for "Christmas Movies" or "Halloween Movies" for example.
Tip: By the way, I finally created a workaround for a long awaited option to sort movies in my Apps by "Unwatched" using labels and the collections feature. It was a bit of work to mark all of my unwatched movies that way but it's done now. Plus I have to remove the label on any we then watch, but at least I can use channels exclusively now. At least I was able to sort them that way in the browser so I only see the ones I need to mark that way.
