Sync files in images folder

Hi all,
I started a new project with 8 files in the IMAGES folder.
As I progressed in the project I copied other graphic files into the folder (now there are 26)
The problem is that in the remote IMAGES folder (on the server) I alway see only 8 files (the initial ones).
Of course I also tried to manually delete the entire project folder on the server, but without solving.
Has anyone had the same problem as me?

Do you have IMAGES listed in the extraFiles property?
