I have Ubuntu X64 running and I have installed dolphin and packages like kffmpegthumbnailer, mplayerthumbs, ffmpegthumbs mainly found here. Even after that I cannot see thumbnails. Any idea what's wrong. Check the screenshot below :

I had exactly the same issue. I used

sudo apt-get install kio-extras

and now it works well. You might need to go to

Settings>Configure Dolphin...>General>Previews

and then select whatever you need. Then of course press the "Previews" button if you haven't or go to View>Previews, but at least images should be by default. I also read that for some other formats (that I'm not using, so I haven't tested it) you should try

sudo apt-get install ffmpegthumbs

sudo apt-get install mplayerthumbs

sudo apt-get install kffmpegthumbnailer

I hope it works for you too!
