how to customize an icon for a usb stick on mac and automount a dmg file?

Question

I want to make a custom icon to a usb stick on mac and show that instead of the ugly blank icon that exists by default

as I have to compile a presentation I want the users to be able to quick access a html file that I have on the root of the stick.

how can I accomplish that?

Answer 1

Copy the image you onto the clipboard, select the item (USB Drive), File > Get Info, select icon and paste the content of the clipboard.

Edit: As for automounting, the system is already auto-mounting the USB stick you're plugging in, so I guess I don't understand that part of the question.
