I have 3 separate photos on my computer that I would like to group together to make it look like 1 photo, no gaps and the same size.
How do I do this please?
Assuming you are using Windows 10 or 11 you should have a program called Paint 3D already installed. This guide tells you how to use it to stitch two photos together but there is no reason why you can't use the same method to stitch three

Alternatively, if you have a friend who has Photoshop - ask them nicely and whizz the photos across to them
