Div to upward?????

blew is image of templates Im trying to make.. Im having a prob about div.. that div currently is backward, how can I bring that to upward to others??

 

Use z-index. Btw, image seems to be larger in width.

 

yeah, image is larger, I have been using large images but now i will reduce the size.. but for older post I must do something.. thats why Im putting them above other div so that people will be able to see older posts
