I have absolutely no idea whether this is technically

all formatting would be related to font size. Presumably the user sets the
font to a comfortable size for them, that tells you how good or bad their
eyes are, and so you would want to scale up all images proportionately.
As far as I know, the image size is always provided to the browser in
pixels but I do know that browsers will behave differently when
resizing a document that contains images. When I hold down "ctrl" and
roll the wheel in the middle of the mouse to zoom in or out, it will
make the text appear larger or smaller, but in some browsers (such as
Opera, but not Firefox) it will also scale the images.
There might be a practical reason we would want to force the size of
an image to remain proportionate to the text, like if we are
displaying images (non-unicode symbols...) mid-paragraph, as part of a
sentence. Egyptian hieroglyphics would be one example, but I don't
foresee a reliable hack for something like that.
