Can immutable be a memory hog?

Let's say we have a memory-intensive class like an Image, with chainable methods like Resize() and ConvertTo().

If this class is immutable, won't it take a huge amount of memory when I start doing things like i.Resize(500, 800).Rotate(90).ConvertTo(Gif), compared to a mutable one which modifies itself? How to handle a situation like this in a functional language?
