Postman Windows app vs Postman web interface

I am new to Postman.

  1. I have workspace, and a collection within that workspace. Using the Windows app, I have defined two variables in the workspace. I cannot figure out how to see these variables through the Postman web interface.

  2. I have placed an image file in my %HOMEPATH%/Postman/files folder. How can I see this file through the web interface? (I assume the image file is sync’ed to my Postman account.)

Thank you so much.
