Support WebP Image Format

WebP a next-gen image format which reduces image sizes.  It would be nice if OwnerRez supported it.  File sizes are typically smaller and more efficient.

Current blog Masthead images are fairly large in size and only support PNG, JPG, JPEG, GIF, BMP, & ICO formats.

This suggestion was recommended to my site by PageSpeed Insights, which is a tool Google suggests for page performance optimization:
