Hello,

few software supports the transparency while importing TIFF rasters. The
best way I have found to maximize the transparency recogintion is to use the
alpha-channel of TIFF. This works in many Geographic Information Systems
(GIS) as MapInfo or ERDAS Imagine. I don't really know how to set the
alpha-channel using Photoshop under Windows environment but it should be
possible. Check TIFF or Photoshop manuals for additional information.

I hope that will help you for your work.

Best regards
