Where do they get these pictures from , one i just had to click on has a 2nd photo in it which looks like a missing person photo ,?

I'm afraid I haven't seen her at all. Sorry.

This is a confusing question

You must be dumb as ****.............

I'm confused as to what you're talking about. Please provide a link to whatever you're referring to so that we (I) can provide a proper answer.

With that said, placing a small photo within a larger photo is quite simple. All you need is a photo-editing program/app like Photoshop, Gimp (free @ gimp.org), DarkTable (free at darktable.org) or any other program that utilizes layers. Layers is the ability to have multiple photo placed on top of the others while at the same time being separate. For example, you can place a small image of someone's face over another image of a forest. Because the photo of the face is on it's own layer, you can then manipulate that photo in any way you want without affecting the background image of the forest. In your stated example, one could place the image of the face over background image (which is its own separate layer) and then resize that image to be small. Then, because it's on its own layer, you can move that image of the face anywhere on the canvas (canvas refers to the entire image area of the photo). Then once the image of the face has been resized and repositioned, you can then flatten the image (means by which the image has only one layer) and save it as a jpeg to be uploaded to the web or printed.
