How to add a picture partly into a video

Hello,.

So, I'm currently making a 3 minute news film at school, and am trying to add a picture into a video,

so at the beginning of the news, I want to add a picture either right up or left up corner of the video

something like this...

so,,, how do i insert a picture like that into a video?

and, additionally, is there a way to make it look like when transitioning the screen, the picture would magnify and fill up the screen.and the film begins

so in the example, the bread/snack picture would enlarge, fillup the screen and another video would resume.

thank you.
