Adding a photo to a report is no different from adding any other element to a report. To add a photo, click the Image icon in the Toolbox and then click somewhere in the appropriate header section you want the photo to appear:

Navigate through your computer to find the picture file you want to insert into the report, and then click OK. The image will be inserted full size into the report:

Click and drag any of the outside black boxes to scale the picture to the size you want, and then make sure the Size Mode field is set to Stretch in the Image Properties window.
