I'm new so I apologise if I have posted this in the wrong section. My slight niggle is that I dragged a jpeg file from a folder onto the desktop in order to set wallpaper, but it has centred on the screen and has not tiled to fill the available space. As the image is a vertical strip approximately 5 pixels wide, it appears as a vertical line in the middle of the screen. There is nothing in the appearance menu about wallpaper, and I have not successfully found a way to tile it, so can anyone tell me how? Thanks.
