my AUD 0.02 (legally the defined value is 0 on its own, but it can be 
combined to give it a real value)...

This seems like a sound approach.

One possible way of storing the longdesc information is using annotea - 
http://www.w3.org/2001/Annotea

This uses RDF to hold the metadata about a URI, so it is relatively easy 
to get the description in the language you want, and equally to create a 
form-based interface to create data. There are a number of 
implementations - as well as the stuff listed on the site there are a 
collection of java tools for building clients, and some C++ stuff as 
well (both built for student projects in France - I need the time to get 
the routines listed :(

A similar possibility is RDFPic - tools for including information 
directly in a jpeg and extracing it again, compatible with Adobe's XMP 
stuff. And open source, crying out for extension to PNG, GIF, SVG...

I'd be happy to help with a Spanish version of the interface, and can 
look around for some other languages (my primary ones are french, 
spanish, italian and english, but I like learning :)

One of the benefits of making this stuff explicit is that it is a lot 
easier to search for images by an actual description than by the fact 
that there might be relevant words nearby in a page (apparently ho 
google's image search works).
