When you insert a picture into a AutoShape, Excel automatically sizes the picture to fit the shape. You can change the size of the picture, if necessary, by dragging a sizing handle. To move the picture within the AutoShape, click the picture, and then drag it to a new location. If you want to move the AutoShape but keep the picture in place, click the AutoShape, and then drag it.
You can also use the Picture Tools Format tab commands to crop, compress, or delete the image.
Compressing pictures can reduce file size and improve performance when working with your workbook over a network or on a slow computer. You can compress all pictures in your workbook or just selected pictures.
You can also change how text wraps around a shape or object by clicking Wrap Text. For more information about wrapping text around objects, see Wrap text around a shape or object.
