Here's how to upload pictures with Photobucket.com
(Hopefully you know how to get the pictures from your device to your computer)
First go to the site and make an account.
Once you log in find and press the upload button.
Press the big green button here so you can select what you want to upload. Depending on the size you can do several at once. But if the picture is big, like from a digital camera, it's best to do 2-3 at a time.
Once your photo(s) is uploaded go back to "View Album". Your album is where all of your pictures are. Hover over the picture you want to post on the site and some links will pop-up under that picture. Click on the last link. Doing that copies the image code and all you need to do now to post your picture on here is paste the link.
The BnB ad was by complete accident and I think it's awesome!
Hope this helps.
