Yes. This would also be the case if you cloned your SSD to another SSD or a (large) flash drive. The only real difference is that with the clone, you'd be able to plug it in, choose it as your boot media, and get going again instantly. Meanwhile, with an image, you have to restore the image to a drive.
Another important note is that in order to clone, your destination needs to be as large as or larger than your source--you couldn't clone a drive with 100 GB of data on it to a 64 GB flash drive. You might be able to put an image on the flash drive though, depending on how well it's compressed.
