Can't change background image

Question

Hi guys
I am using NWBC for desktop 4.0 and can open transaction UI5/THEME_DESIGNER and all is great.
2 issues though
1. when i navigate top my index page (as a copy of sap corbu) i click on background image and I get the popup with the 2 squares (one for + image and one for 'No Image'  I drag a gif or a jpg file to the + square and I get error "File Reader undefined"
2. I can change the background colour, text colour etc and save as draft and then publish - the publish seems to work (get green tick and sucess message) and then i enter THEME_NAME in the NAME field of table NWBC_CFG and then in the VALUE field I enter Copyofsap_corbu (which is the THEME_ID i see on the publish popup but on restarting I don't see any background colour change or anything.
Am i missing something here ???
Many thansk in advance

Dear Silvia,
That note released just 1 month before I think. And that solved my problem.
Actually there are some other notes also we implemented prior to this note.
Here I will copy paste some imp conversation from SAP Support Team. Hope it helps to you.
"we strongly recommend to implement the latest notes for the UI theme
designer, please see SAP Note 1852401.
In your system the version 1.2.0 of Theme Designer should  be updated
to version 1.2.2 . Please implement the Note 2010406.
After implementation of the note, please try again to load NWBC
Previews."
"As I thought the NWBC previews pages have a small issue which was
corrected in SP09 ( your system is currently on SP08 -
SAPK-74008INSAPUI). For this reason the parameters for NWBC pages
could not be loaded in theme designer and you see quick and expert as
empty."
"please apply note 1986795 once it is released. This should fix your
issue."
"I found the weak part in the code that is responsible for truncating
the theme data and created a correection for that. SAP note: 2051350
Please import this note into your system and then rerun your scenario.
If this does not solve the scenario please feel free to reopen this
message."
" update the note 2051350 and added the manual activity of
creating a data type in transaction SE11 according to the screenshot
that you attached."
"Please download the note in its new version 2, process the manual
activity, and then import the automatic code correction of the note."
"could you please implement the note 1990723 into your system and
retest it again.
If you still should  experience problems re-open this message."
"We try to find a problem and give you a solution asap, but in your
scenario are involved more as one software component ( ABAP, SAPUI5,
ThemeDesigenr, NWBC, etc.) which should coordinated and works
together. Moreover the individual setting in your system bring more
complexity what needs a time. Sorry for that.
The problem for a now is obviously somewhere in HTTP Configuration,
instead of cache token the system send in a background the logon page
(see attachment).
And I would like to ask you to implement again one note 2021480."
