Microsoft Office Picture Manager isn't included in recent versions of Office, but you can use Word, Outlook, PowerPoint, or Excel to edit photos in place inside an Office document. These apps have many built-in photo editing features, so you might not need a separate program for the basic photo-editing tasks you want to accomplish.

After you insert a picture in your document, click it, and then click the Picture Tools Format tab.
In Word, you can choose color variations, crop, compress at different levels, and apply some special effects.
