Comment:

 Attached patch `wp_get_attachment_image_alt.diff` works in trunk (revision
 10347) with no errors.

 Patch uses attachment excerpt as alt text ("caption" field in WP 2.6 media
 interface) if non-empty; otherwise it uses the attachment title. (There
 was no "caption" field before 2.6, so attachments created then probably
 have empty excerpts.)

 I also added a new filter hook, `wp_get_attachment_image_alt`, so people
 can choose some other alt text if they like.
