Ok, here we go. Download "Photobucket" from your iphone app and input the info to start your downloads. Once your done go to Upload Media. this is down at the bottom. You can either "choose existing" or "choose camera" and download your pics. Now go to "My Albums" at the bottom and hit "photo". Your pics should be there. Tap on the photo you want to download. Here comes the detail part, at the bottom righthand corner is a "i" symbol in a white circle. Tap that. Tap the IMG link, and it will say "Copied IMG Code. Hit ok. Now go to the forum and "reply" on a topic. Hold your finger where you post a comment or picture. The paste button will pop up and hit it. The "link" will from the Photobucket will be there. Now post.
Photobucket has other things on it but for me one step at a time. As for downloading pics from your iphone on the road, this should work. I'm headed on a trip in 2 weeks and will post stuff along the way.
