Hello Dalton Coble,

Now, as you can see from my username, I am no Ben Jakuben. But I think I might have an answer for you. First, it would be much faster to reply if you were to give us the code, but that is okay. Second, maybe you can use (if/else if/ else) conditionals to set photos for every fun fact, and, good idea. So, I will only use three fun facts "President Obama is the 44th United States President" and "Russia is the the most populated country" and "The Washington Monument was a site of a hostage incident", (Yes, search it up, or search someone named Norman Mayer, age 66). And I am going to use corresponding pictures. Lets Start! :-)

String[] facts = {
              "President Obama is the 44th United States President",
              "Russia is the most populated country",
              "The Washington Monument was a site of a hostage incident"
}

Random randomGenerator = new randomGenerator Random()
int randomNumber = randomGenerator.nextInt(facts.length)

fact = facts[randomNumber]
<your textView>.setText(fact)

//Now this is where the Images come through

(ImageView) <your imageView> = (ImageView) findViewById(R.id.<your imageView)

//Make sure you have your three photos in your drawables folder

if (randomNumber == 0) {
android:src="@drawable/obama"

//And so on

I get what it is doing on here but when I put it in my code I got errors. you can get the same code I am using from the android course how to build a simple android app and use that to show me if you want. I get errors when I put in your code.
