I'm a newbie, but here is what I've found out;
I too have DLd custom .png files to use as logos, and I found that if you dont't make all upper case letters to lower case, it wouldn't work for me. I hope this helps. Any thing you DL to the "customlogo" folder will have to be lower case when you copy it to OOTP logo folder.
