 When wp_get_attachment_image() is called, it generates the alt-text from
 the post_excerpt field instead of the (new) postmeta field with meta_key
 "_wp_attachment_image_alt". This causes the alt text to not be set even
 though the media editor clearly states that the "Alternate text" field is
 being used as alt text for the image.

 I have attached a patch that corrects this by calling get_post_meta()
 instead of post_excerpt inside the function.

 As a fallback it would be good to expand the function to check if there is
 an alt-text entry, and if not use the caption (post_excerpt) field
 instead, or if only the Title is set use that.

 The alt text should not be empty at all.
