How to change the photo upload of app to local photo album upload?

In order to ensure the authenticity and validity of information, some apps don't have a button to upload local photo albums, and they can't be modified. Even if the source code of the program is modified, the remote server can be found. Once modified, the APP may not be installed and used normally.
