In some of my questions in Arqade (e.g. this), I would put a screenshot to indicate what I'm talking about.
I was wondering if I should write the text in the screenshot in the question's body to get it indexed by search engines. Or will putting the text as an image description or link description also get them indexed by search engines (both external and SE's built-in search functionality)?
