The WCAG defines text alternatives as

Text that is programmatically associated with non-text content or
referred to from text that is programmatically associated with non-text
content. Programmatically associated text is text whose location
can be programmatically determined from the non-text content.
Example: An image of a chart is described in text in the paragraph
after the chart. The short text alternative for the chart indicates
that a description follows.
(http://www.w3.org/TR/UNDERSTANDING-WCAG20/text-equiv-all.html)

Thus, according to this definition the in page equivalent must be
associated by a short description in the alt text of the image letting the
user know where the alternative is located. Basically there needs to be
an programmatic or textual association between the alternative and the
image.

Subject: [WebAIM] Alternate text for images having caption adjacent

Dear list members,

Greetings for the day.

Many of you might have known that I write articles on various
accessibility topics, happenings and technologies at www.maxability.co.in.
Recently I have published an article on "Writing appropriate alternate
text for images" at
http://www.maxability.co.in/2014/05/writing-appropriate-alternate-text-ima
ges/.
Interestingly I got a comment that says
If alt="" is set to image having a caption describing the image adjacent
to it , how does the screen reader user know that an image is available in
the page. When alt="" is used screen reader completely ignores the image
and the user will not even know the presence of image.
Any thoughts on this will help me in correcting the article and provide
the best possible information to the readers.
Feel free to comment as reply to this email or to understand the context
