If you want to lower the file size of your GIFs you can do that easily here >> https://ezgif.com/optimize
Funny, that's just the site that I've been using. I have done that optimization, as well as shrinking. But the size problem with these particular gifs is due to having many frames, 2 months' worth. Because it's the first time I've posted them, I wanted to start at the beginning of the season. The next batch will be maybe 2-4 weeks, something like that. And I guess I'll put them on the melting thread but make them click-to-animate (>700 px wide), so they don't consume much bandwidth for those who don't wish it.
