Ah, that's probably what I'm missing.  Even better, all I have to do  
is duplicate the existing tfw file from the original image (the client  
likes tfw files) with the Photoshopped file name.  tfw+EPSG = warped

Right.  My brain is a bit scrambled right now, with all this.   
gdal_translate doesn't generate the error, gdalwarp does, after I've  
used gdal_translate to assign the srs OR after simply converting the  
original image.
