photobucket is the best hoster I've used. they make it easy to post pics.
heres how to post from photobucket....
from your album, simply copy the address in the "Img" box of your pic.
then paste it in your reply. you don't have to use the Img buttons here because they are already in the address you copied from photobucket.
this is why you see many pics posted that have "img" on both sides, looking like this

hope this helps.
