General use of the images is explained in ›FAQ93 - read it !

You get all the images in web resolution within a week or two after the session.
If you want some images in higher resolution that is fine.
Just remember that:
1 i can not give you hi-res of the images which will be used for stock (Getty Images) - that could lead to serious problems. therefore, you will have to wait until those images are selected.
2 for maximum effect you want those images processed - retouched, colour corrected etc - that takes time. i would not, of course, ask money for processing them, but you might have to wait...
