We do not provide this image in a higher resolution. If you want to use any of our icons from the demos you can download the Demos zip file and find the icons in the resource folders of the examples' solution. The Demos zip file can be found under the UI for WPF download page in your account. However, this page is available only if you have an active license for our products.
Also, if you need any image that shows our demos you can open the demos application
and create screenshots. In addition, you can take a look at the Color Theme Generator
