I get a great picture of myself but I can't do anything with it. Is there any software that I'm supposed to download?
It depends on what you want to do with your picture. The file is saved by default in the (C:) > Users > Your Computer Name > Pictures directory. If you want to edit the photo, I suggest you try utilities like Picasa, PhotoScape or Photo! Editor. All three of them are free of charge and easy to install and use. If you want to create complex designs, you can try Adobe Photoshop.
