Welcome to the forum!
To get rid of the aircraft photos, use Tools | Show Photos/Details
To remove the vertical display window, either use F8, or Map | Vertical Tracking Window
If you don't want to ever download or view the photos, you can also use File | Preferences | RadarBox and deselect Download Aircraft Photos.
Also, if you are using Radarbox without an Internet connection, and the menus seem slow, goto Fil | Preferences | RadarBox and deselect "Share Flight Data" - you'll have to do this each time you run Radarbox as it defaults to on for when you use the Internet.
Have fun!
