I'm trying to build a site around Coraline, and I want to use the featured image as a part of the site, but I need to reduce the default size of the image from 990x180 to 853x100. Currently, if you try to upload an image via the Dashboard it forces you to crop any image that doesn't conform to the default size or its aspect ratio.
I've looked through the PHP and CSS files, but I guess I'm overlooking something. This is one of those things that should be an official option in my opinion, but for now I just need a workaround.
Site link: Right here in case you need to see it.
Thanks a lot!
