Elfinder / Ckedit Images Not Showing As Thumbnails

One annoying thing about elfinder file browser (as used by ckedit wysiwyg editor) is that when browsing the image folders, PNG,JPG etc images sont show as thumbnails, instead you need to click preview for each image to see it!

Is there any way to add/enable thumbnails in elfinder, so it shows thumbnails like this:


... instead of just showing icons?:


Wow, is no one else crippled by this issue.

Its impossible to see which images are which just by looking at the icons.

It seems that the thumbnails are not even being generated,
