I read online comics and usually the hilarious punchline is in the alt-text but iPad misses out =[ My solution: Currently when you tap and hold a link it shows the URL above the options you can select from. This could be extended to tap and hold images. It's the same layout of options (save image, copy) and some alt-text would neatly fit above those and be consistent with the UI! Thoughts and comments? Just putting it out there. I'll go see if I can find Apples suggestion drop box.
