Hi Caleb,
Are you referring to the header background image? If so, there is no option to "stretch" it. It's best if you upload a header background that completely fills up the entire header. This means the size of the header image should be the entire size of the header.
For example, if the header size has a height of 150pixels and length of 240pixels, then your background image should have the same dimensions. Thus, when you upload the background, it occupies the entire space without having to stretch the image.
If the image you'll be using is small then you need to "stretch" the image to the same size as the header using photo editing tools like Gimp and Photoshop before uploading it to the theme.
Hope that helps. Have a good day!
