If you insert a shape and a picture into a Word document, you may want to group them together for the purpose, for example, of copying and pasting.
If you try to group them together having just inserted them, you may well find that you cannot even select them both. The problem arises because the default setting when you insert the picture is that it will be in line with the text.
Select the picture, then on the Picture Tools Format tab, in the Arrange group, from the Wrap Text dropdown, select one of the other options, most likely Top and Bottom. You are then able to select both the picture and the shape by holding down the Shift key. Then, from either the Picture Tools Format tab or the Drawing Tools Format tab, in the Arrange group, click the Group dropdown and click Group. The picture and shape will then be grouped together for copying and pasting, etc.
