Both methods work. But, in the first case, you will have some frames rendered
with null ImageComponent2D. With double buffering, you can get continous
updates.

You can change the by-ref image right after detaching and Yes, you need to call
set() for the changes to be reflected.

No, you don't have to detach to change the image or the size. You will have to
set the capability bits to change the image(ALLOW_IMAGE_WRITE) or the
size(ALLOW_SIZE_WRITE). if you want both changes to be reflected in the same
frame then you need to do it from a behavior
