Replying to Need help extracting images off Wii message board!

In We Ski and Snowboard, I have some sick shots that I would love to share with NS, but all I can do with them is send them to my message board, and when they're there I can't even export them to an SD card! I already emailed nintendo and they were absolutely no help, pretty much stating that's impossible to do. So if you know of a way that I can get these photos off my Wii's hard drive (I would assume they have to be saved somewhere on the hard drive for the message board to retain them) and onto either a USB stick or an SD card, or if you're not that techy, you can at least recommend a site that can possibly assist me better? Don't even mention Yahoo Answers as they were even less help. +K to helpful answers!
