Do you have photobucket?

If not, set yourself up on it at Photobucket.com its free, and gives you a really easy way to upload pix to your own holding area, then copy the URL from the pic and paste it into a Post of PF.

Really easy, once you set it up, uploaded your pic, copied the URL, pasted it into this Post, it'll show and i can then do te same having resized it....
