Placing a business card with no code

I am seeking help on how to place a local business card (image) on one of the prime spots on my site. I have no code. and the spots are setup to accept code, unlike the post an ad where you can upload a image with no problem or code. I am using osclass with the gum theme. There must be someone out there that has done this, although maybe not with the gum theme. If you have done this? Can you provide the steps you took starting from the image, how you got it to the site, the file you installed it in, etc till the final product installed on your site. I am looking for main page insert or wherever really. I know each theme and installation will be different but I cannot find any tutorials on how to load a image with no code into those prime spots, Of course I probably am googling for answers using the wrong terminology?
