As already known, it's not possible for iOS users to select image files to upload from Safari on iPhone, because the browse button to display the "select file"- dialog is disabled. It works fine on Android, but not on iPhone…
What is the particular reason for that issue?
I heard that the browse button is disabled because there isn't a file browser on the iPhone. Someone other said that Safari just disabled root access. Is there any reliable source which explains the issue? (I need it for my thesis.)

iOS apps can only read data in their own directory and thus only Safari would be able to use these files - so how could you create them and put them in Safari's directories?
