this was great advice thankyou on google images you need to click the picture because the preview isnt the full size

that hasnt worked i have tried this with multiple pictures now and none seem to work https://gyazo.com/9107f94ab71dcc80a373b1a23e1cdc44 that is a pictue of whats happening and i really dont know what to do and the picture is definately 2560x1440

every time i try to add a 2560 x 1440 background it changes it to 300x300 i dont know what to do
