Yes, all images in the library are loaded in RAM with the library.

In general, an icon image and the appearance of a button using the
image appear different: the borders don't look the same. However the
appearance of a button whose icon is set to the id of an image will
be same regardless of whether the image is imported into the stack or
referenced from a library.

I think I did just that somewhere in the early evolution of
Serendipity Library...shortly after I had occasion to have to change
an image. In Serendipity Library I took it the extra step of
referencing all the images instead of importing them into the
library. Now I can "instantly" change all images by switching
libraries, or change one image by replacing the image file in the
folder.
