Problems with Uploading Different Pictures in a List in Firebase

Hey Guys,

I am building an app for a uni project. Where multiple people can go to different tagged places on a map and upload a picture (to a firebaseDB) from there with the according tag. After that a picture of another person who also uploaded is shown.

Our issue is when uploading the pictures in the FirebaseDB is that the tags are all the same so the old pictures are deleted. Another issue we have is that we don’t know how to show a random other picture from that tag to the user.

Use a date code or milliseconds timestamp for each new image

Get a taglist and select a random item from the list returned

Hey,

Thanks so much for the reply!!

We aren't really sure how to do those things. We are pretty new to MIT App Inventor. Could you maybe give us a bit more info on that?
