[Q] boot_logo topic

I think I'm pretty versed in this stuff and I have a clue - but all the info I find on the subject says I should find the boot_logo.bin file in /system/media/images
Trouble is, that folder don't exist and I am unable to find the file that shows me the bootlogo image.

I am currently using the LiquidSmooth latest L ROM but suspect any of the others I test, would have the same folder/file structure. Anyway, I can obviously change the logo image by fastbooting pre-made ones but I want to make my own. Problem is, Logo Builder does not work like all the info I have seen on it. The Make button never lights up. Program seems to load the logo.bin file I initially feed it but that's it. I don't get it.
Anyone ever dabble with changing their boot logo image successfully? Appreciate the help, must be something simple I am over looking.

I did manage a cool bootanimation.zip that turned out nice, especially if you're a
US Marine - or used to be...
