Well you can do this for sure with this script.
I guess you create your members yourself?
then simply do this.
1. go into admin-->settings and higher the dimension for the member buttons ( the buttons or photos in your case during the join form ) or leave it blank to have no maximum width and height.
If you create your members yourself, you simply need to enter the url of the photo into the banner field on the join form. Even if you dont add them yourself, then the member have to enter the url to their photo themself
2. by reading your last post it looks like you dont need the voting buttons at all on member sites, go into admin-->settings and select the ranking method Hits out / Hits salida. Now the member with the most clicks out is ranked #1
3. do what is told in the link i showed you. its the fix for your out problem
and by default, the links and banner / photo are clickable
P.s i only mentioned the buttons because you said hits in dont work
