currently, any webclips created for a xf installation are rendered as fairly unattractive screencaps.
its a simple matter to include a graphic, but this is something that should be addressed in the core (particularly with a mobile style coming soon).
ideally page_container would insert one or more icons depending upon the resolution of the device being used. it would be great if these icons were referenced in style properties as well, with an option to upload a single graphic to be gd-processed into different resolutions for the various devices.

a more complex method (bearing more satisfying results) can be found here:
