Need help with simple code

[Bob Bedford]

Hello there,

Little problem I can't solve. Its seems easy but I can't find out a simple
solution. Maybe a clever way already exists:

I've a site where people may have up to 5 pictures.
They can add, remove, change pictures as they want. The problem is when
users remove pictures at beginning and in the middle.

User X uploads 5 pictures.
Then he decides to remove picture 1 and 3.
Actually the resulting pictures are 2, 4 and 5.

I want to move (by renaming) the pictures to have finally 1,2,3

How can I do this ? Pseudo code would be great, as Actually I'm trying to
look in 2 array to keep trace where they are free slots and used pictures
and trying a complex move between array. Isn't a good way, I know, but I
can't find a easy way.

Well the siplest way ( I think ) would be to include the shifting
process into the delete function. So when you delete image 2 then you
will run through a loop that runs from 3-5 and shift them all so the
result will be 2-4. BUt since I dod not quite know how your code is (
if you allow more than 1 deletation at a time ) I can not quite tell
you the solution, since if you are deleting2 files at a time you have
to run the proccess 2 times ( or something like that ).

Hope this answares some of your questions ( although it raised some
more in my mind, :p ), and hope I undestood your question. :)
