Image swapping script scale issue question

Hello 

I have a script below which I have been working on - it allows the user to select two things and swap the sizes. 

For example you need to swap the main image with a drop in image - this allows for the swap to happen with one shortcut.

The bad news is I am having a hard time getting the images inside frames to fit portionally once swapped  they still have the old sizing and do not adapt for the changing frame sizes. 

Any help on this would be great!

Many thanks

The samples below show the script before and after using coloured boxes and then a sample with phototos and the issue that arrises.

Before

After 

they have swaped placed 

and an example with photos below 

before

after  - it looks like there is nothing there but it because the images have not fitted proportionality

when I fit them myself i can see that they are there  - would be good if the script could also do this part so then the user only needs to adjust the crop to their liking

            // Resize the image proportionally
