Is that ugly or not? And in specific how to get rid of this from my website(s)? I don't mean only MY personal windows explorer but I don't want to have it there in any way! Check this out: http://www.caribbean-junky.com/caribbean-junky/caribbean-transportation.htm Who knows how to?
Yes, thats right. If you don't want users with the skype plugin installed to see numbers like that you can use images for the numbers, (although this is not advised).
As others have said, you are the only one who can see it. I don't believe the majority of people that visit your website have that skype plug-in installed so you should be fine.
