I use Google/Picasa for my pics. They can b easily set to public or private. Even if a picture is in a private folder, I can still post it for every one to see with a direct link.




in the link for the above picture, there is text "....vN0/s480/IMG_8644.JPG"  I can manually change the size of the inserted picture by changing the value s480 to for example s1024, s640 and so on..
