First, welcome to the forum. Putting images in is pretty easy, though it requires an external host for the images. You can create a free account at a site like Imugr and upload the pics there. Then you just have to put the link to the image in the post body inside image tags. To get the tags, just click or tap on the little icon that looks like a picture. Videos are added the same way, but you need to upload them to YouTube and use the Flash tags, the icon left of the image one.
Awesome! Thanks a ton!
