Templates are useful when you are working over and over again with same page layout or settings and you can use them as starting point then change settings, picture or anything else to produce something new but with same basic layout.
This depends on the type of image you're attempting to bring into Illustrator.For jpg, bmp, gif, and other pixel images, you can use File > Open > filename.jpg and Illustrator will open a new document with that image as the first object on the page.Or, with Illustrator open (but not maximized) you can grab a file on your desktop and drag it into the illustrator window. If you have a file open, Illustrator will drop the contents of that file onto the artboard as if you copied and pasted it. If you have no illustrator files open, it will create a new illustrator document with that image as the first object on the page. This will also work with PDFs.
