QT, C++ and how to connect it all with the client-server?

Question

C++ / C#

Hello everyone!)
I asked myself the question of how to connect my knowledge of c ++ with the client-server method of the
script that I want to execute, and is the concept of client-server generally suitable here?
A user(1) can upload a photo and another(2) user can edit the user's photo (1)
This is in short
Where do you send it? where to dig?
I will be grateful!)
