We are enhancing mapserver, especially adding geospatial
analysis capabilities. One of the ongoing efforts is to
add a link between mapserver and RDBMS/SQL, so that
users can access mysql tables directly from mapserver.
What I am not sure about your posting is that storing
extended data types in mysql (like points, lines and
polygons, but images - yes)?. My experience shows that
object oriented databases (like Jasmine ODBMS), or
object relational databases (Oracle 8i, PREDATOR etc)
are more suitable to store geographic entities, than
systems like mysql. Second problem is to access 
(speedily) these data types you need some or other
extensions (like R+ tree) of indexing structures
supported in these databases. Anyway we will let you
know once our interface to mysql is complete.
