Photo help please

My old "pooter" died (thats what Cameron calls the computer). Sanat bought me a wonderful new laptip, but with it, I don't have the photo software I used to have. I downloaded Picasa and like it, but for some reason what I saved on Picasa isn't what uploaded to photobucket. I've been playing with editing and saving for hours. Don't even get me started on the whole cropping and sizing thing. :mad:

Anyone have picasa and tips on whats going on? I'm frustrated and confused!
