Posting pictures or video is real easy.
You need a digital camera.

A connection from the camera to your computer, USB or card reader.
A FREE account at a photo sharing site like
PhotoBucket or
Flickr there are others, I use these two.
Take a quick lesson at
Photobucket's Uploading Help Page There are several ways you can upload at photobucket, Their "bulk uploader" works great! with this you can upload a whole folder with two clicks of the mouse.
So give it a try. Show us your photo's.
