I watched carefully the tutorial by Vitaliy ( http://www.wolfram.com/training/videos/CDF002/
), as well as the screencast (http://www.wolfram.com/broadcast/screencasts/cdf-embedding-in-a-nutshell/
) in Wolfram´s CDF website. I followed the procedure given in the first of them in order to embed an interactive image in Blogger, using Dropbox as the host for the .cdf and the .html files. The .html file produced by the SaveAs|.html contains references to my HTML files which have to be saved in the Dropbox public folder (something which is omotted in the tutorial) as well as a few other things (v.g., the Java scipt snippet produced by the wizard for the .cdf file has a lot more code than it appears in the example given by Vitaiiy, etc.), so that I had to make a number of adjustments, which given my extremely limited knowledge of Java took some hours of work. The thing is, when all this stuff is finally incorporated in my blog, and I hit the Publish button in my computer, it works fine. But..., if someone else (who doesn't have Mathematica or the CDF player installed on his computer) tries to open it, he gets a message asking for him to download the CDF player...
Well, I thought the above-mentioned procedure was meant precisely to avoid this (I know that downloading and installing CDF player is quite simple and may be achieved in a few minutes, but most people I know hate to do it). I have the very simple question: is it possible to prepare an interactive example and embed it into a blog - in Blogger, or Wordpress or whatever- so that any user (who most probably doesn't have the CDF player installed, let alone Mathematica) can open it and play with it without being required to download anyting?
