How do we know the true shape of Galaxies?

This one's making my brain hurt.

Given the enormity of galactic bodies, doesn't it follow that (unless we're lucky enough to regard a galaxy at an exact right angle to its plane of rotation) the light from its more distant edge has taken aeons longer to reach us than that from its nearer edge?

Consequently, doesn't it follow that the "flat" images our telescopes are seeing are hopelessly distorted versions of what's really there?
