[mapguide-users] Image download size

We currently have an issue with MapGuide with the size of Image download
when viewing Aerial images or detailed raster maps, we are finding the
average PNG download is 2 - 3 mb, this makes for very slow web client when
working over the internet.
We know you can change the image format and have tested JPG and PNG8, but
the image degradation is to great, I'm not sure how much the proposed
ticket http://trac.osgeo.org/mapguide/ticket/465 will help with this.
We have experimented in using Base maps, but we really do not want fixed
So I wondered about a compromise, where the vector data is downloaded as
PNG and image data is downloaded as compressed format, similar to using
Base Maps but without the tilling, the PNG is then overlaid on the raster
image. Does this makes sense?, would it be feasible for the a future
development? The idea is you zoom and pan as normal for a non tiled map.
