amending/replacing images

Sir
Please advise how to
(1) remove the ball from the background image.
(2) replace the images in Shop (both thumbnails and the big one)
(3) replace the three images found in the circles - 'It's Game Time, Learn to Play, Shop Golf Equipment'

Thanking you for the continuous support and advice.

Best regards

Indira
