Thanks for tip. I tried that, but it didn't help. I have noticed some failed dependency error messages during vagrant up. I took a screenshot of the errors: http://i.imgur.com/8EZCrl6.png

Hey, sorry for late answer. I tried this once again and I noticed, that it actually works, but only in Firefox. It's quite possible, that I was previously using chrome...

I personally like dropzonejs: https://github.com/enyo/dropzone
