If you include an image in your paper from a source that clearly states there is no attribution required then you do not need to include an in-text reference, reference list entry or copyright note. Include a Figure number (i.e. Figure 1) and a title above the image. A note below the image is optional.
If the source states that attribution is required, include a Figure # above the image, then include a copyright statement in a note below the image and a reference list entry.

If you are not including the picture, but only referring to it, include an in-text citation, i.e. (Bracco, 2006) and a reference list entry (as above).
