Alpha channel transparency for GDAL Image formats

I'm using GDAL manipulate an image, eventually ending up with a georeferenced TIFF.  I load that tiff with:

IMapImageLayer iml = (IMapImageLayer)_mapArgs.Map.Layers.Add(txtb_saveLoc.Text);

which works.  However it does have the no data parts filling in around the edges as black.  Is there any way I can get that no data border to disappear? 

 

Thanks
