How to make user pick a photo and then rename it and save?

I want to have the user pick a photo from the device gallery or take a picture using camera.
then they must rename the picture in the kodular app, the app suffix the date then enable the user to send the picture to online storage by press of a button

thank you

what have you tried so far and why is it currently failing?

just do it… and in case you got stuck, then post a screenshot of your relevant blocks…
you might want to use the image picker component, camera component and file extension

A very good way to learn App Inventor or Kodular is to read the free Inventor’s Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps … the links are at the bottom of the Web page. The book ‘teaches’ users how to program with AI2 blocks.
There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .
