Can I Apply Object Styles to Change Frame Size Without Resizing Images in InDesign?

This is a newbie kind of question. 
I'm just trying to dab into Object Styles but I have not found the expected InDesign documentation with regards to this feature? Sorry for the French UI but this what I'm using :

All I want is to "store" the width and height of an existing picture frame to apply to other picture frames in my page. But as soon as I apply the style to any of the frames I'm trying to change the size of, the placed image gets "resized", proportionaly? I don't want the scale of the contained images to change. All I want to do is to change the size of the picture frames themselves.

But I guess this is not a job for Object styles?
I know how to do this without using Object Styles. I was just curious to find out whether Object styles coule do the job easier.

Thank you in advance for you kind help and please excuse my ignorance.
