Where do I put downloaded button files?

You cannot add buttons to the toolset.  What format are your buttons in?

You cannot add the to the Inset menu. If you want to create custom buttons, add a bitmap (for example he one that represents the Normal state, then add new states and replace the bitmaps. Here is some info on working with states: https://community.articulate.com/series/articulate-storyline-2/articles/adding-and-editing-states-in-articulate-storyline-2

They're .png files. I suspect they are sets of multiple images that work as Michael Hinze described.

Thanks for the help!

Thanks, I'm on it.

Hello Mark!

Welcome to the community! Glad Michael and Phil got you sorted here.

Thanks for the nice welcome, Emily!

I am mightily impressed with the response time.

I expect to become a fixture around here. I haven't done much authoring in a long time and I'm sure I'll become quite a pest as I get back up to speed. I did my first authoring on a Hazeltine MicroTICCIT in the mid-70s. The last tools I used were Quest, C++, and Authorware and the last time I did serious authoring was about a year before the initial release of Flash came out.

Authoring has certainly gotten a lot easier over the years. You young 'uns have done a good job with it. :D

Glad you are happy with the products and the community so far Mark!

Just post in here if you need anything else!
