walk me through photo sharing

My family is throwing a surprise party for my dad and we thought it would be nice if we could make up cards asking guests to upload their pics to a photo sharing website.
The only problem is I've never done this. What websites do you use? Help!!

I used shutterfly for mine - just go to shutterfly.com, click the link at the top that says 'SHARE' and then register yourself for the website. All you have to do is create a usename and password - it's free - and then you make your share site!

i made my website address [first_initial last_name.shutterfly.com], so you might want to makes yours something like that, so it's easy to remember.
