Content Placeholder and Picture Placeholder display the pictures differently
I need the Content Placeholder to respect the size I created in the master, but instead, it resizes the picture once put into use. It would be great that the picture is inserted (or at least have the option to) the same way as in the Picture Placeholder, filling all the space with it, instead of shrinking it.

That's the whole point of having two different placeholder types. If you want the behavior of a Picture placeholder, use a Picture placeholder, not a Content placeholder.
