what we do

the general assumtion is that the aplication has one Path to store imiges on the server.

under this path there can be any subdictionarries(user)

we store the the path beginning under the generel Path in a Tabel.
so if sombody moves all Date to his notebook we only have to change the Path to the grafhics dictionay in the Path variabel(Unser can do this ) an all Pictures are there again with another location.
