Consider the place that your pictures have been uploaded to (such a PhotoBucket) the true location of your photos.
If you go somewhere else (such as BYC) and do something to let others see your pictures in your posts, it's kind of like giving the people who view your posts (or blog) a pair of magic glasses that let them see your photo, even though it hasn't moved from its true location.
That's the best explanation I can give without using a whole bunch of geeky computer terms you might not understand.
