Help Me: I'm Technologically Illiterate!

Now, many would think that, as I am twenty years old and living in the computer age, that I would know the ins and outs of computers and be able to do anything with one. This is, unfortunately, not the case. It is only by the grace of God that I'm even able to use the basics of Blogger.

Now, as I am an aspiring cartoonist, I would like to post my attempts with using construction and other drawings. However, I don't know how to use the scanner. Now, I could probably learn to use the scanner part, but I need to know how to upload all of that stuff I want to upload, like my construction drawings and my collection of comics.

Next, I need to know which program allows you to overlap the original source of a drawing and a person's copy. Also, how do oyu upload film clips and film snaps? I ask for the help of my friends on Blogger (Joe Bloke? Fellow cartoonists?)

Just leave me a comment and that will help.
