Well Im not too sure how to resize them. I can resize photos which I have taken but for some reason it wont let me do others.

To get the photos to display on the message board like I did for you, all you need to do is copy and paste the link thats in the "IMG Code for Forums & Message Boards" box into the text of one of these messages.

Basically if you click the link that you set up http://tinypic.com/view.php?pic=s47w3q&s=4 there is some links on the left hand side...thats the one to copy and paste
