I've been playing around with the ImageBrowser (Editor) and would love to see a variation of the ImageBrowser as a standalone widget. If I could use it without the Editor to simply select or upload an image file that would really add value to some of my applications (for which I now have to use a different tool: elFinder). Since the ImageBrowser already exists, hopefully this would be an easy addition to the KendoUI toolset! :)
Found issue in ImageBrowser.php, for thumbnail, getThumbnail uses setImageHeaders, which send whole image size, not thumbnail size, causing thumbnail loading delay or fail (depending on browser)
