Yak, Digital Camera

I just received a Digital camera today, and would like to ask someone on the
list, what size should I use for the pictures, I want to view full screen at
home, and yet be able to send via e-mail smaller files. Also I will want to
be able to use it for ebay selling, with the regular picture and the ability
to click for an enlargement. Does anyone on the list know of a URL that
explains all of this, or send me some comments offlist.
Thanks,
bill
