It is not trivial, but not too hard either.

It is not trivial because Org first produces the images and inserts  
org-style links. Later, in a second step, these links are replaced  
(formatted for HTML).
One way to solve this is that `org-format-latex' will add this  
information
as text properties to the link.  Then later, when the HTML formatting  
is done,
the text property could be retrieved and converted into the attributes  
you are mentioning.

You have worked on org-format-latex before, I think this should be  
relatively easy for you.
