A picture can be added to a word processing document, a spreadsheet, or a presentation. Adding a picture to any of these document types requires two components--(1) information about the picture itself, and (2) information about its placement within the document. The former is common to all document types, and much of the XML for this information is within the main drawingML namespace (xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main"). The information regarding placement and positioning within a document, including the high-level elements and the non-visual properties, is specified in separate namespaces and varies based upon the document type . See DrawingML Overview for more on the namespaces.
A picture is specified with a <pic> element. The namespace in wordprocessing documents is in the picture namespace of drawingML xmlns:pic="http://schemas.openxmlformats.org/drawingml/2006/picture". This is what is used for most of the sample XML on these pages. In spreadsheets, it is the spreadsheet drawingML namespace xmlns:xdr="http://schemas.openxmlformats.org/drawingml/2006/spreadsheetDrawing". In presentations it is in the main presentation namespace xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main".
A picture can have such characteristics as border, resizing behavior, overlaid fills, and other effects. A sample picture within a word processing document is shown below.
A picture has three basic components--the fill or content that fills up the picture rectangle, non-visual properties, and shape properties. Spreadsheets and presentations also have associated styles. These components are specified with the elements below.
|blipFill [BLIP = binary large image or picture]||
Specifies the type of picture fill that the picture has. A picture has a fill already, but if the picture has transparent pixels, it is possible to add another fill within the <spPr> element by specifying, for example, a gradient fill. See Image Data, Tile or Stretch Image to Fill, and Effects for details of blipFill.

Specifies non-visual properties of a picture, such as locking properties, name, id and title, and whether the picture is hidden. See Non-Visual Properties for details.

Specifies the visual shape properties that can be applied to a picture. They are the same properties that can be applied to shapes. See Shapes - Visual Properties for more.

|style (only in spreadsheets and presentations)||
Specifies the style that is applied to a picture or shape and the references for each of the style components, such as lines, fills, fonts, and effects. See Shapes - Styles for more.

A <xrd:pic> element within a spreadsheet document can have the following attributes.
|fPublished (spreadsheets only)||Indicates whether the picture should be published with the worksheet when sent to the server.|
|macro (spreadsheets only)||Specifies a function associated with the object. E.g., macro="DoWork()".|
