I believe the only way is to do some math on the server or on the client (with 
javascript code).

You already know the map extent and jpeg size, don't you?

You can find a lot of examples on the net, just look at the js code of one of 
the many webgis clients (p.mapper, openlayers or ka-map to cite a few).

Regards.
