As you note, screen readers don't always identify graphics. You
shouldn't necessarily avoid images just because they might be
identified.

Why two spans? Wouldn't one work? You are using <del> and <ins>
regardless of the lack of support, correct?

While users may see the text in Option 2 if CSS is disabled, they
would see the same text in Option 1 if images are disabled. I'd maybe
put the text in parentheses to help offset it in these cases. Beyond
that, either option looks OK, though clearly not as good as if screen
readers actually supported these elements. And I can't really think of
a better option. I'm more of a minimalist, so I'd probably go with
Option 2.
