By zoomed in do you mean that they are larger than when you open them on your computer? If so, I think it's not that they are larger so much as the program you use to open them on your PC auto-sizes them to some default size for viewing, but that the file is in fact as large as you see it posted.
Did that make sense? Recap: most likely the picture is the size you see when you post it in photobucket. The reason you see a difference is because the program you use to download photos and view photos from you camera automagically re-sizes the photo for viewing without changing the 'actual' size.
