relation between fields image field to a "Link to a URL"

You were right all along ggppdk....

I was over thinking this I think. In the image field I used in the prefix:
<div class="bio1class"><a href="{{Bio1_url##0##link}}" class="fusion" target="_blank">

in the suffix:
</div>

the div "bio1class" positions the image properly and the class "fusion" is used with the NoNumbers Model plugin to render a popup window on the link.

I also added custom css of
.fusion {
opacity: 1;
transition: opacity .25s ease-in-out;
-moz-transition: opacity .25s ease-in-out;
-webkit-transition: opacity .25s ease-in-out;
}

.fusion:hover {
opacity: 0.5;
}
to add the fade effect to the image.

Thank you so much for all your help !

thanks for return and mini tuto !
