Translation of mosaic images

Select an image by clicking on it. To select more images click on each of them while pressing Shift. The selected images are shown with a surrounding red box. Click on a selected image with the left button and keep it pressed while moving the mouse to drag the images to the desired position. Once you have correctly located them, release the button. Make small translations, using the arrow keys. Each time an arrow key is pressed, the images are translated one pixel in the direction of the arrow. If you keep the key pressed, the images are translated until the key is released. This tool is usually used in combination with the Transparency and Rotation tools.
