Does the online version let you use custom fonts?
The Laughingbird's downloadable Software allows you to use your own custom fonts you may have on your own computer.
However, the Online Graphics Creator does not because it's a "browser based" app, the browser code forbids us from "looking" onto your personal machine.
It won't let our app (or any 'browser based apps) access a users folders, like fonts. Otherwise, others could use the connection to inject all kinds of evil onto your machine.
So, everything is separate from your computer. "in the cloud"
Which is why we invented to 800 Google font thingy.
Hope this helps a bit.
