Here is a screenshot of my code so far and how the image is stretching to accommodate the screen size. How can I make the image look better? I’m EXTREMELY new to Lua and if someone could explain to me in heep a deep hur dur (very simply) I would be so appreciative. Thank you!
You may have forgotten to include that screenshot, but that’s alright. 
When posting code, please use the code formatting options here on the forum, i.e. the <> button.
Now, without seeing any of your code, I’m guessing that you are using a very small image or you are using display.newImage() instead of display.newImageRect(), the former of which does not automatically scale. Just in case, you might want to read up on:

and

If my guess didn’t answer your question at all, then use the code formatting options and show us some of that code of yours.
