Where does APP Inventor store images

Continuing the discussion from Encode an image and pass it to a database:

What is the URL of an image you have uploaded to APP Inventor so you can call it from an external php script ?

Do you mean an asset in the media folder ?

...is stored in the assets (internal storage) at least with the compiled app (APK/AAB).

Not Acceptable! An appropriate representation of the requested format could not be found on this server.

I get this when I run the APP but it works fine when I send the image directly in the URL ?

If this is with a compiled app then it will not work, if you have hard coded the path...

tell us what you want to do and what you have done, better with screenshot of your blocks.

I want to send images from APP Inventor to an external MYSQL server. This code is close.
