2015 NAIP imagery not adding properly - How to fix?

[Albert Pundt]

I've been trying to get the Pennsylvania 2015 NAIP imagery into JOSM as
Bing is horribly outdated in most areas, and USGS takes so long to load the
tiles it's unusable.

However, I can't seem to add the layer properly. I enabled remote control,
and used the link in this <https://maxerickson.github.io/NAIP_Remote/> page,
but the layer seems to be offset horizontally by half the width of the
world, and an odd flickering Pennsylvania in the middle that doesn't appear
at all at anything but the lowest zoom levels. Upon further
experimentation, it seems to do this for all the states' layers. Here
<https://www.youtube.com/watch?v=xmNy6HJFZWQ> is a demonstration video
showing this odd problem, and here
<https://help.openstreetmap.org/questions/54606/how-to-add-2015-naip-imagery-for-pennsylvania-to-josm>
is my question about this on help.osm.org that I posted in addition to this
email.

What do I need to do to make this work?
