animato video

As previously mentioned, I have created an animato video. For some reason, my computer will not let me link it to my blog. However, I was able to link it to my Facebook page.
Perhaps, whatever is keeping my computer from linking my video is the same thing that is not allowing me to paste a screen shot. Could it be something that I have not completed on my blog? I have been trying to screen shot all day; I will try any advice anyone has. Thank you for your help.
