Or the entire Last of Us game.

You don't need to do that anymore. You can just hover on the desktop now, and you can long-press on mobile.

Oh, cool, that's good to know.

You can't long-press in News+. OTOH, you can't see the comments in News+...

I use the official apps.

Not everyone does.

Also that feature used to work in the official iOS app but is broken currently

Wait, what? It is?

Looks like it works fine in the latest beta. I don't have the old app to check, but it will definitely work when this beta gets released.

Also, for the record, I like folks who share the Alt Text. It gives a place to just talk about the alt text, which for a comic as popular and single-paneled as XKCD, is a nice benefit.

@samuel: looks to be hardware specific. On my iPhone 6S+ long presses on images do nothing – the menu never displays (I tried with and without 3D Touch enabled) — but after powering up my old iPhone 4S, I confirmed that the same version of the app works there. Both devices are running iOS 9.0.2.

THANK YOU! I check my feed on my old iPhone and there is no way to see the alt text at all, even directly on the site. I really appreciate you doing this!

They are right. It's broken on my 6S as well. Long press no longer works.
