Try disabling bundle optimizations, what happens is that the path to the bundled css stylesheet conflicts with referenced images. For example. You might have a css file /Content/css/style.css => in a bundle "~/Content/css" in which an image is specified as such
.someclass { background-image:url(img/someimg.png) }
This would resolve the image to /Content/css/img/someimg.png
Now you deploy the release build and the css file is now rendered to a bundle URL such as /Content/css Now the image URL resolves to /Content/img/someimg.png
You can change this behaviour in App_Start\BundleConfig.cs
System.Web.Optimization.BundleTable.EnableOptimizations = false;
