Since most mail systems have an upper limit of 10 or 15MB per message (including attachments) your friend may not be able to send you more than 2 or 3 full-sized photos per mail message. That can be very inconvenient.
With
Pando.com she can send you any number of full-sized photos/files upto 1GB per 'shipment'.
With
Podmailing.com you/she can send
unlimited size files/folders!
(But is your internet connection fast enough?).
