Step 3 and 4 are the same and I think they are actually the final step.
After you download Picasa You make a folder on the Picasa website that you will share with
Webmaster@wsrconline.com ,"AKA Roy Barrow". That is where you will be storing your pictures. After you have download Picasa, if you right click on a picture you will have an option called upload to web albums. I just been selecting photos and selecting the upload to web albums. It puts it in an album named Drop Box on the Picasa website. Then I move those pictures to the Anthony's Addiction folder and a few hours later they appear on our website. I am not sure if Roy Barrow has to do anything to them or not.
I don't think you even have to open Picasa on your computer once you get the online album set up.
I may have just made it sound harder than it is. But it really is not hard once you get it setup.
