Clickable picture, setting it up,

for a campain, how do i set up a clickable picture, the picture url, how has it to be setup ??? i can not get it to work properly

Are you doing this with Jarvee through Campaigns? Did you set your clickable image post server?

You can achieve the same thing by adding a normal post from Campaign What To Publish tab. Add your caption and the url in the Caption field. Then go to Campaign Overview > Advanced Settings > check this option in General tab:

Publish the post.
