Have you tried anything yet? there are a variety of ways of handling this. You just really need a kind of collection (array, arraylist, etc) and a smartly written for loop or nested for loop that keeps track of the dimensions of the images.

"Would I use an ArrayList and store all the images in there or would I just use a for Loop."
If you use an ArrayList, you still need a for loop to display the images!
An array list isn't necessary if you know in advance the number of images and don't plan to change it.

"create a class grid...where you call the grid cell and input an image."
Why not, it can make the code tidier. But the loop you shown will still be in the grid class. Perhaps it can delegate the loading to the grid cell class, either way is fine.

About your code: why do you create two Tile objects per image?

@PhiLho The reason it creates two tile objects is because I am trying to create a matching cards game, so basically it will display two random pairs and the player has to guess where the matching pairs are.
