GOT IT!
I misread. 1024x1024 (not 1024x768)

*goes off and re-learns reading*

 :lol:

I am getting a green background. Music worked
Confused on a step:
It states the following:

Once you have finished editing your file save it in your directory:
WoWInterfaceLoginScreen

and name it:
Background.png

Now all you have to do is drag and drop the .png file onto your BLP Converter
and remove the .png file out of the directory.

image saved as a png format 1024x768
I saved it to the LoginScreen as "Background.png"
the next part is blurry...
do i put the converter in the LoginScreen folder then drag/drop the png on it then remove the png leaving the blp file? (did that, screen is still green)
do i copy the png image to where the blp converter is at (currently it is in the interface folder as per extracted file put it), drag it on the blp converter, then move the blp file to the login screen?

if your confused  - now you know I am LOL

Ok, but seriously, I get a green screen no matter what i do, with a blue/white checker square lower left
I read somewhere that either the path is wrong or the file is bad. I did it with 2 files and still come up with the same probl

Thanks if you can help me make this work!
