Hi John,

The "Alternative (Text only)" field in the Options tab in the Picture
dialog contains the same value as the Title field in the Description
dialog. However, the Options tab in the Picture dialog provides no
field for a long description.

The name field, as far as I know, is mainly used internally. If I
rename it, I always make sure to use a value that would be a valid ID
in HTML (i.e. no spaces, first character can't be a number, ...), so
the ID is usable after I export the file to HTML.

In a presentation, does it make a difference whether you have given
the image a name or not? In Impress, images don't have a name by
default, while Writer automatically generates a name when you insert
an image. (And when you have more than one image on the same slide
and you have given each a name, you can reorder them in the
Navigator. I would expect that this determines in what order
they/their text alternatives are read out by a screen reader.)

On Windows, IBM Lotus Symphony appears to be much more accessible
than LibreOffice and OpenOffice.org because it uses IAccessible2
instead of the Java Accessibility API (and some other UI work). If
someone is willing to compare the accessibility of the Mac OS X
versions of IBM Lotus Symphony and LibreOffice, I would be very
interested to hear about their findings.

Oh, and please give AccessODF a try ;-) :

Best regards,
