Project Raster Problem

When reprojecting images the output images are left with a black border or lines at the image edge.(Screenshot attached.) 

I am projecting from a "NAD 1983 StatePlane New Jersey FIPS 2900 (US Feet).prj" into a "WGS_1984_Web_Mercator_Auxiliary_Sphere.prj".

These lines exist on the source images as NoData.  However it seems the re projection is assigning them actual values (1 or 0 as the input and output images are .tif images in G4 compression) instead of leaving them as NoData or assigning them the background value. 

What is the best way to stop this from happening?

Or possibly force the transformation to assign the Nodata values to the background value instead of the displayed value??

Any help would be appreciated.
