Blogger Button???

I have been trying to figure out how to attach a button.  As you can see, I have attached TWO images and no link!  Obviously the first image was TOO BIG!  I think I need a little help on this one.  I'd really like to figure this part out, so I can network with others with the same interest.  Maybe one day I'll be "up and blogging".  In the meantime, I'm prayin & perseverin, as usual:)
