Is there someone to help me with setting up my app?

I have created all the pages to my app however i am not understanding how to take a picture and have it populate in an image box and add gps capture if it us possible. I also need it to email me everything from the page once the info is submitted. Can someone help me make this possible. I have never built an app before.

For sending email you are going to need a 3rd party tool. I use SendGrid personally.

Take Photo flow function works just get the filepath from that to use as the Image source.

You can get GPS coordunates from polling the sensor (see documentation)
