The idea is good but there are hundreds of details to consider, first, when creating gifs it takes time for each movie or series that exists and that is a lot of work. Second, that not everyone will like the idea of not being able to control which image to see and being forced to repeat the gif and that is tedious and third, the quality of a gif drops a lot compared to how photos are uploaded on the site. I hope my answer is helpful.
Thank you for the comment, and yes it's was very helpful. I guess I was thinking I needed to add "something" to the site to make it more "interesting". Actually I'm glad to hear that what I have been doing is good enough.
Now that I think about it, loincloths are simple ... and so should the site be also.
