first part correct.
second part: no link needed using PB. On PB you download using the brouse feature like you used to do for pics on the this forum. Once your pics are on PB there is a setting for what media your posting to and that allows your pics to be seen without having to have a hot link.
I hope this is better. I'm no computer geek so some of terminology might be off. If you get on PB and goof around for a bit you should be able to get it.
