Hi, and thank you for any assistance you are able to give.

I have read every "font" related post I could find on this forum multiple times, searched through the user docs multiple times, watched the video by Flop, tried the copy/paste suggestion from ddt, am using FireBug and even tried changing the name of the font file from "Bank Gothic Light" to "Bank-Gothic-Light" wondering if the spaces affected things due to not using " marks in the font-name part of the CSS but I could never get my "live-edit" to change on the fly like in Flop's video.

I tried placing the .ttf file in the root folder of the site, in the root Piwigo folder, in the Themes folder, and 2-3 other folders. I tried making the "live-edit" changes to various parts of the Sylvia theme (Block headings, links, maybe others I don't know how to properly name).   8-|

I can not find anywhere on the web or Piwigo forums that simply says what fonts you can and can't use, and if you want to use something special, where to put the file. What am I missing?

Again, thank you in advance for any help!  :-)

For simplicity:
Theme = Sylvia
Font Being Attempted = Bank Gothic Light.ttf
