fckeditor doesn't recognize html code?

hi, i’ve seem to be having a problem with a widget http://www.roytanck.com/get-my-flickr-widget/ …. I copy the the code, and it doesn’t do anything. Check my website http://www.maufotografia.com/ on the “contacto” tab, right side, next to the twitter icon…

could it be that the website is on flash ?
could it be that the admin editor for pages is the FCKeditor and it doesn’t handle the html code properly ?

tell me what you think…
