People on Neocities tend to use stuff like catbox and mixtape.moe, but you can also use Dropbox with a little fiddling
^^^ On the Dropbox thing, if you switch the &dl=0 to &dl=1 at the end of the URL, it becomes a direct link. I don't trust catbox or mixtape, since I think files go bye-bye after a bit. Use Dropbox.
Thanks to both of you. I didn't ask for any reason in particular, just to know it for any future usage, so thanks!
Was hoping you'd get rid of the frames sooner or later. They're such a mess.
