Adding and cropping images the right way to an existing map

Hi,

I would like to know, how or better to say in what way I can / should add images obsolete ones taken after a mission flight. when importing them I see the green dots on the map where the pictures have been taken and the bounding box is always resetting itself to a standard size rather than to the previous area I have chosen.

my question is how do I adjust the boundary box to have the same result I had on my first flight of the mission.
the purpose of the obsolete pictures were a better 3D model and more detailed orthomosaic image.

any info on that would be great.
