Bring an image group to front and acess to individual images in a group

I create a group like that below, for creating the walls in the map permanently

local images = display.newGroup()

for j=1,20 do
      for k=1,20 do
                if map[j][k]==1 then

                    local block
                    block=display.newImage(“wall.png”, size*(j-1), size*(k-1))
                    block:setReferencePoint(display.TopLeftReferencePoint)
                    block:scale( size/24, size/24)
                    images:insert(block)
                end
      end

end


There are a function for update the screen when something hapens, for example, the hero moves…

function update_screen()

    – draw background

    – draw hero

    – draw other elements

    –    BRING WALLS IMAGES TO FRONT  *

end


So, how can I bring the whole image group (all images in the group) to front at once ?

If I can’t, so I need to bring all individual images in the group singly, so I need to access them but I don’t know how.

Help me, please

Thanks!

images:toFront()

images:toFront() does not work…

It should work so you must be doing something else too
