Have you ever placed a picture in your Word document, only to have the picture not be visible when you are later working in the document? This seems to be a common occurrence, and there are several reasons for this.
Word implements what is called a "layered" approach to documents. Each document has several different layers. You are probably most familiar with the text layer, in which your text actually resides. There are two other layers, as well. First is the header/footer layer, which contains both the header and footer information that appears on every page in your final document. The other layer is the drawing layer, which contains graphic objects.
In reality, text can appear in all three layers of your document. For instance, headers and footers are composed primarily of text, text obviously appears in the text layer, and text boxes can appear in the graphics layer.
Similarly, graphics can appear on all three layers. People don't normally place graphics on the header/footer layer, but they can. Graphics are much more common on both the text layer and the graphics layer. If you place an inline graphic in your document, it is on the text layer; if you place a floating graphic in your document, it is on the graphics layer.
What does this discussion about layers have to do with whether pictures show up in Word? There are a number of ways to view your document, each accessible from the menus or by clicking on one of the View buttons in the lower-left corner of your screen. Most people do their writing and editing in Normal or Print Layout views. If you are using Normal view, Word displays only the contents of the text layer of your document. Thus, any pictures residing in the header/footer layer or, more commonly, on the drawing layer are not visible. In order to see the pictures on these other layers, you need to switch to Print Layout view. Of course, some pictures are visible when working on your document in Normal view. Why? Because some pictures—inline pictures—are stored on the text layer, and this is the layer being displayed.
You can switch a drawing from the drawing layer to the text layer (or vice versa) by changing whether it is floating or inline. You do that by following these steps:

1. Right-click on the picture to display a Context menu.
2. From the Context menu, choose Format Picture. Word displays the Format Picture dialog box.
3. Make sure the Layout tab is selected. (See Figure 1.)

4. In the Wrapping Style area are several options. Choosing In Line with Text places the drawing on the text layer; any other choice places the drawing on the drawing layer.
5. When you are done making your choice, click OK.
