Making a link in a template

["SteveLord8" <webforumsuser@xxxxxxxxxxxxxx>]

New DW8 user here and I am just starting to learn web creation. Anyway, my 
department's website is here.

 http://medicalboard.iowa.gov/

 I would like to make the top bar be a permanent link to always go back to the 
homepage with the "Welcome" message. Now I edited that image in DW8 so it 
should point to the index.html file, but when I Save it and Upload it to the 
server and then run my cursor over it, it doesnt change to the little hand.

 How can I fix this? Thanks experts and web gurus.
