Blog home page images

Hi. I’m just wondering if there is a way to have a standard image that shows on the home page if a featured image is not added to each post.
As it is, if I don’t add a featured image, the excerpt shows on the home page with no image next to it. I don’t always have an image immediately available for a post so I’d like to have my logo or something similar that would show as a default next to any post that doesn’t have an image attached.
Is this possible to achieve, easily?
If not then I’ll find another solution.

Cheers.
