Or,
Step 1: Drag the image you want to insert to the timeline, such that the image touches the start of the second video clip before which you want to insert the imageand a blue line becomes visible, this indicates that the start of the image is fully aligned with the start of the clip (hence the end of the previous clip)
Step 2: in the menu that is opening select: insert and move all clips
Step 3: by stretching the image,
you effectively want to change its duration, so select the image and click on the clock icon above the timeline and change the duration settings. You can probably do that more precisely than by stretching, although stretching as Koen41 and AVPlayVideo write, might be faster
