Image game : explicit buttons "Not sure" and "No more pictures"

[Hsarrazin]

I guess the 1st one is for I don't know and the 2nd is for none of the unselected pictures (which then removes the item from the game), but I'm not sure...

in other words, which button should I use when : * I found an image, and I think that no more is needed ? * I did not find any image and none of those proposed will do (i.e. only works by a painter, not his portrait, or only a symbol, like for Bruno Bettelheim) ? * I found an image but some others could interest other contributors ?

Does the "Not sure" button removes the selection I did ?

Also the game does not count items where don't know bas been hit, even if 4 pics have been added (coat of arm, maps, prononciation...) It should count for 1 if pics have been added, even if the main pic bas not been chosen, when there are a lot to choose among ;-)
