I agree with MonsterMinis on this. She's normally spot on with her gar info.
As for pics, it's really easy. When you're in the text box to type stuff, the top of it has a bunch of stuff you can click on. The third thing from the right is a tiny picture of a tree. Click on that. You have two options: from computer or from URL. Click on from computer and select upload files, then select the picture you want to upload.
