 yeah, you could test each variable value/add new ones from here related to pvr (https://kodi.wiki/view/InfoLabels) (channellogo) to see if one works for u, u can add an empty conditioned value to test if all fails, eg, <value>IMAGEPATH</value>.
If it's not even in the db, then obviously kodi won't be able to get it with a native method but u can add the path manually, even in the skin - general idea, <value condition="String.IsEqual(CHANNEL_TITLE_VAR_IN_SKIN,CHANNEL_TITLE)>imagepath://CHANNELLOGO.PNG</value>  

Ok I am sorry I am a bit lost now, if I am understanding you correctly.  You are saying use this (NPO 1 HD as example)...

<value condition="String.IsEqual(CHANNEL_TITLE_VAR_IN_SKIN,NPO 1 HD)>imagepath://NPO 1 HD.PNG</value>

The part I am not clear on is where does this go, what file?  Also what is CHANNEL_TITLE_VAR_IN_SKIN or how do I find it?

Thanks for the help.  

Try the following:
(a) edit includesFooter.xml:
search for #id "44123", this control should show the logo in the footer.
dry-test: put some picture in the skin's media dir, and copy name+extension to the texture tag, eg 

Code:

<texture background="true">test.png</texture>

Run kodi and see if u see the image in pvr windows (and the window u wanted specifically)

(b) return the original texture in the above control and edit includesVariable.xml:
go to "<variable name="channellogo">"
add this line:
note the channel's name in the string.isequal param should be exactly as u see it in kodi, the png can have whatever name u want. as long as u give the correct path (or just name&extension if u put in under media dir in the skin's dir).

Code:

<value condition="String.IsEqual(ListItem.ChannelName,NPO 1 HD)">NPO_1_HD.PNG</value>

If it works, then u can add as many as u need for each channel, just change name &png path, and u're set.

not the most elegant solution, but a simple one. 

This works, thank you so much!!!  You are the Man!!!!
