to make your picture show up you first have to save the picture in a *.jpg format on your computer
then you have to signup at
http://www.photobucket.nlafter you signed up and have yor account activated you go to my albums and you set the location of your *.jpg picture file and click the big upload button
then your photo is added to your album
just copy the img code thats below your photo in your album
and then paste that img code whereever you want in your profile or in posts to make the photo appear
and if you only have the html code you have to place
tags around the address
good luck
