>_<:If you master the ways of mapping picture,then this problem is not
problem!Just using your head think some logical method.
>_<:Here,I use a array save
where and whith picture should show.For
example:use array mapindex save information.then when you map these
pictures,only need to calculate the real position and then move it to the bufdc
,finally put it in the mdc (here bufdc in charge of making an
exchange between every picture and mdc)
