Graphics in Word 2010
By default, Word makes objects snap (jump) to an underlying grid laid across the document. If you drag an object, such as a shape, you'll notice that it moves in little jerks rather than smoothly. This is because of the grid - but because the grid is normally invisible, it's not obvious.
A callout is a type of text box that also includes a line for pointing to any location on the document. A callout is helpful when you need to identify and to explain parts of a picture.
Including a large number of in-line pictures in your documents slows down Word's performance. You can improve performance by replacing actual pictures with picture placeholders.
In most cases, it is recommended to use Visio to create diagrams, but in some simple cases, such as company organizational charts, you can successfully use the built-in Word tools.
There is no need to use an additional image editing software in order to create high-quality pictures for your document. Instead you can use Microsoft Word picture editing tools to correct and improve your pictures.
Use the AutoCaption feature if you want to add captions to all items of a particular type automatically.
