To me its easiest if you size down the photo, save it to your desktop and then when you "browse" for the file to upload it will be easy to find and quick to load. Let me know if you need any assistance. If you have a set of photos , you would do better to put them onto Airstreamphotos.com in your folder, and then people can see them through your photo button link.
There are lots of threads about it but here is a rcent one with some more info
