Hi,

I'm not sure if I can ask this question, but I think HMS only supports georeferenced files (with X,Y coordinates).

Your bmp file is about some DEM? This is what your quetion is about? Is a raster model?

If so you can convert it into a shapefile and then upload it as a background image.

Give us some details and will see if I can help you out.

Rodrigo.
