Witsoart,
Both images will still show in the page, the one you specified and the default. However, Facebook should only use the first one it sees for times where it needs one image (the Like button). One thing I noticed in the code below is that there is a opening Javascript tag at the top, for some reason. That shouldn't be there, but I don't think it's the cause of your problem either.
Either way, please use the Facebook Debugger tool for your URL, instead of just looking at the HTML to see what Facebook sees:
developers.facebook.com/tools/debug
Hope that helps
