I've spent ages trying to put a new photo on here, BUT for some reason it's sideways on and I can't work out how to have myself standing rather than levitating - please can some GN'r who understands how computers work, explain to me how I can go about changing the photo from sideways to upright?
Most computers have some built-in photo programme in which you can find a facility for rotating a photo. Your photo will probably open in it automatically. There is likely to be an icon at the bottom of the screen that looks like a circular arrow and you click on that.
If you cannot find one, download Paint.net at any of several sites (e.g. downloadser.com/paint-net/) - it's free - and it does everything that Photoshop does. Go to "File" then "Open" and select your photo; then go up to the top bar and click "Image" and a drop-down box will appear and one of the options is "Rotate photo." You then have to choose in which direction to rotate.
