@xoxogay A good uploader will usually include thumbnails for each video with large collections, sometimes in their own folder so you can preview the content at a fraction of the size of the full download. I'm fortunate that I have good enough speeds to be able to keep my ratio fairly steady even with the large collections, but I think this should be a thing for all collections with more than, for example, 20 videos.

yas that help
one I looking at has random thumbs on post but impossible to say what file is what thumb
