At closest approach the spacecraft was turned around traveling engine first...they didn’t take pictures because of that and the fact that the burn to slow down to get into an initial orbit was more important than pictures. Juno is in a highly elliptical initial orbit so it is traveling away from Jupiter now. That’s why the Jupiter looks distant...it is distant.
The whole mission has a highly elliptical orbit due to the radiation belt around the planet. The space craft essentially dive-bombs the planet once each orbit and captures a slice of imagery. It is going to take about a full year to get all of the pieces of the images captured to complete the survey.
Here is a video of the orbits planned https://www.youtube.com/watch?v=3liQOvj8LPE&feature=youtu.be
