When I click on last comments I get the list of comments. When clicking on a picture, I get another picture and not the one displayed above the comment!

works for me as expected
Strange, I logged out and in again and it worked OK!
Weird stuff!
an explanation... if you open the last comments and now someone actually comments on a picture then the (relative) pic ids (pos) change. Just try it... reloading updates the pos and all's smooth again
