[mapguide-users] Image download size

[Kenneth Skovhede, GEOGRAF A/S]

You would have to do some development yourself, and I'm predicting that 
it will be difficult.

If you are trying to implement an application that has more than basic 
features, I would recommend that
you look at Fusion 2.0, as the WebLayout is customization hostile. 
Things that are easy to do in Fusion
are difficult in WebLayouts, and often require changes to the underlying 
template files, which in turn, will
break on later updates.
