Trying to create both Image and Text including Array?

Hello everyone, i'm making a game where player will find a location via a text (approximately 2-3 paragraphs) or an image (with a drawing of a specific location within the terrain).

I have created a script attached to "Player" gameObject where player can find papers (or notes or drawings) across the map and the current note leads the player to the next one.

That's why i want to put 'string' variables and 'image' variables into one variable (array, arraylist and list) .

In c# we can create an array or a list of object which can contain multiple type of variables in one container (object[] collection = ... ) but in unity i couldn't manage to do it.

So any help'll be appreciated!
