I spent the last couple days trying to figure out how to show the alt text to people on mobile phones and touchscreen devices! I think I've figured it out. Just tap the image. Some older mobile browsers still won't be able to view it. But we are only human.
Oh my gosh you guys, I'm still in TCAF Awesome-Recovery. It was seriously so great. And on my way back to Scotland, I had my first flight without a night; we flew so far north that it didn't get dark. The sunrise over Iceland looked like a prog rock album cover (please insert wizards as needed).
