The IPad Forum is a community of members from all walks of life and from all over the world coming together to share our experiences and to help each other learn about this wonderful piece of technology the Ipad. There is a wealth of information already here in the many threads we have so doing some searches will answer most of the questions you have. If then you cannot find the answer you are seeking then by all means post your question. There are many friendly and informed members here only too willing to help you.
I'd use this Craigslist app. Great for browsing, and you can create add using it, including photos that are on the iPad. If the photos are still on a camera, that's what the Camera Connection Kit is for, getting them onto the iPad first.
There are other Craigslist apps, but this is one of the best, and my favorite of the few I've tried.
It is universal, so it looks good on both the iPhone and iPad, and if you own both you only pay once; all 99 cents.
