Hi, Vic-

You should be able to do this by opening the file with the GIMP, 
right-clicking on the image, selecting "layers", then "layers, channels 
and path." This will open up a dialog box with a sliding bar marked 
"opacity" which will allow you to shift the image from opaque to 
transparent or anything in-between.
