displaying layers without having legend label

[Richard Taylor]

hello LIST

MapServer Question

would like to show relatively small (1x1m) images when
zoomed in and markers at those locations when zoomed
out at larger scales, so that the user can see many
markers when zoomed out, and pick one to zoom into.

how do i have only one legend label for each point and image?
as opposed to a legend label for the marker and a legend label for the 
image.
this takes up twice the required screen real estate

another way to get at this is, in a larger context, is it possible
to display a layer without having the layer label in the legend?

thanks in advance
