Sorry for replying to my own post but the problem was *not* base64
encoding. The issue was that for some reason the array passed into
getInstance() was zero bytes in length. I added a quick:
if( imgb.length == 0 )
return null;
and things work fine for me at least. I'm not sure if I understand why
this is occurring but it works for now.
