you can post an ad on your regional board once a week. To add a link to your website, the website's main page has to have the TER logo on it - there should be a link on the top of this page that will take you to the self help center where you can find the link code and instructions on how to post it.
As for the picture, you need to put your pic on a photo hosting site - I use flicker.com but there are alot of others out there.
take the link to the picture and put it in the picture URL box - make sure you delete the http// that is in there already since your link probably already has it.
as far as link title, that goes with the link above it, if you put your website link in the box that says "Link URL" and then in Link title put in something like "My Website"
the link will show up in blue with the words "My Website" rather than the link url. And all anyone has to do is click on "My Website" to get to your site.
