Uploading and Viewing Image, Audio, And Video

Hey Thunkers!
For all the beginners out there in Thunkable (not that I am an expert,)
I came up with and built an app that uploads audio, video, and image to the cloud and gives you a specific code.
when that code is entered in a text field and submitted, it will show you the image with which the code came. Here is a link To the app.
If any of you want to know how to make the app, I will be sending a tutorial on Thunkable communities later.
Thank you.
